Special fixtures should be designed for small-sized or special-shaped pieces to hold them during cutting. Of course, some small-sized pieces can also be directly mounted and roughly ground to the middle section. For coated specimens, edge-preserving hot mounts should be used. Some thin-walled parts will be deformed when hot-pressed and should be cold-set. Different grinding and polishing steps are developed for different materials.

Tin bronze is bronze with tin as the main alloying element. In addition to containing 3% to 14% tin, elements such as phosphorus, zinc, and lead are often added. It is the earliest alloy used by humans and has been used for about 4,000 years. It is corrosion-resistant, wear-resistant, has good mechanical properties and process properties, and can be welded and brazed well, does not produce sparks when impacted. Due to its soft texture, it is easy to produce a deep deformation layer during metallographic preparation, which brings trouble to polishing and corrosion. Especially in the annealed state, the grains grow and the internal dislocation density decreases. It is impossible to efficiently prepare its metallographic phase using the traditional mechanical polishing method, and chemical-mechanical polishing method should be used instead. 01 Equipment and consumables Equipment Trojan Alpha-202 manual grinder&polisher; Trojan ThetaMount pressure cold mounting machine; MN 60 series microscope; Air blower; Consumables degreasing cotton;φ30mm silicone mold; Trojan TJ2562AB epoxy resin; Trojan PL-W Polishing Lubricant; Trojan SiC metallographic sandpaper(P1200;P2000;P2500); Trojan YS-JP white fiber polishing cloth(8in); Trojan Final Red-JP precision polishing cloth(8in); Trojan 3μm polycrystalline diamond suspension; Trojan 0.05μm non-crystallizing silica suspension; 02 Preparation process 1-Mounting After ultrasonic cleaning of the specimens, prepare TJ2562AB epoxy resin in proportion to mounting the specimen, and then place the specimens in Trojan ThetaMount pressure cold mounting machine for mounting under pressure.

For this reason, 50% alcohol was added as a corrosion inhibitor, so that the corrosion process could be well controlled, and the dripping method was used. In addition, the mixed solution of ammonia water and hydrogen peroxide can also be used as a corrosive agent, and its properties are relatively mild.

Therefore, when grinding, you should start with fine sandpaper as much as possible. The strength of manual grinding must be light, and each sandpaper should ensure that the deformation layer produced by the previous sandpaper is removed. When polishing, the deformed layer produced by grinding should be removed in the rough polishing stage. For this purpose, coarser polishing particles can be used on the hardness woven cloth and carried out for a longer time. Use with lubricant. For fine polishing, use a soft, short-pile polishing cloth for chemical polishing to remove the deformed layer and scratches caused by rough polishing. It is unrealistic to obtain a perfect sample by one time of grinding, polishing and etching. Repeated polishing-etching operations are required under limited conditions. That is, after the scratches appear in the corrosion, the last mechanochemical polishing is performed again and then the etching is performed again, and this step is repeated until there are no scratches. During fine polishing, the speed can be adjusted in the range of 150~300rpm, the speed is fast at the beginning, and the low speed is used at the end. The pressure on the hand should be light, and at the same time do the reverse rotation movement with the chassis. Etched with mild etchants, using the drip etch method. The black spots in the metallographic phase are silica and silicate inclusions.

Zirconium alloys are solid solutions of zirconium or other metals. Zirconium has a very low thermal neutron absorption cross section, high ductility and corrosion resistance. The main use of zirconium alloys is in the field of nuclear technology, such as fuel rods in nuclear reactors. The typical composition of nuclear grade zirconium alloys is over 95% zirconium and less than 2% tin, niobium, iron, chromium, nickel and other metals added to improve mechanical properties and corrosion resistance. Both zirconium alloys and pure zirconium are metals with a close-packed hexagonal crystal structure, which are characterized by being relatively soft and prone to ductility. Therefore, the zirconium alloy is easy to leave a deep deformation layer and scratches that are difficult to remove during the grinding and polishing process. In addition, twinning may occur if the force is not properly controlled during cutting, mounting and grinding. Therefore, the metallographic preparation of zirconium and its alloys should be very careful. 01 Equipment and consumables Equipment Trojan Alpha-600 automatic grinder&polisher; Leica DM2700M metallographic microscope; Hairdryer; Consumables Ethanol;Degreasing cotton; Trojan PL-W Polishing lubricant; Trojan SiC metallographic abrasive paper(P2000;P2500); Trojan YS-JP white fiber polishing cloth(8in); Trojan ET-JP white synthetic velvet polishing cloth(8in); Trojan 3μm polycrystalline diamond suspension; Trojan 1μm polycrystalline diamond suspension ; Trojan 0.05μm non-crystallizing silica suspension; 02 Sample preparation process 2.1-Grinding Due to the good surface condition of the sample,so polish the specimen with Alpha-600 automatic grinder&polisher, abrasive paper P2000→P2500(The surface of the sample is in good condition, if it is not treated, it can start from P400).

The use of chemical mechanical polishing in fine polishing can effectively remove the deformation layer on the surface of the sample to obtain a bright and perfect surface. It should be pointed out that the quality of the customer's hot mounting is poor, and there is a gap between the resin and the sample. In order to prevent cross-contamination between different abrasive particles, it is recommended to perform ultrasonic cleaning between each track. The hot mounting material is not completely burned through and fused, and after grinding and polishing, there are lumps and discoloration, and it is recommended to improve.

In this example, Mo and TiC are sintered, and the hardness of TiC is about 3400HV, which is much higher than 2550HV of SiC. Therefore, SiC sandpaper should not be used for grinding this metal. It should be replaced with diamond grinding disc. Plane polishing is relatively simple, use a hard woven cloth with polycrystalline diamond suspension. During fine polishing, use a soft damped polishing cloth for chemical mechanical polishing to release the stress on the surface of the sample, and pay attention to controlling the time to avoid too much embossing for phases with different hardnesses. After silica polishing, since the stress on the surface of the sample is released to a large extent, the subsequent etching becomes extremely simple, and the etchant can be used to slightly rub for a few seconds. Pay attention to protection, the corrosive liquid is poisonous! In the metallographic phase, the light blue is TiC, the black is the hole, and the white is the molybdenum equiaxed grain. The dark area around TiC should be the diffusion and fusion area of TiC and Mo. Referring to GB-T 41080-2021 "Molybdenum and molybdenum alloy metallographic examination methods" 9.2 grain assessment of 9.2.1 appendix B of the comparative method, the grain size of molybdenum is at or better than M10 grade.

However, coarse grinding discs tend to chip and crack the ceramic, so it takes a longer time to remove the larger pits and cracks on the ceramic surface during fine grinding. Polishing requires the use of mechanochemical polishing to prepare a good surface. If the sample is not mounted well enough, not all the pellets can be ground out at the same time. In order to prevent the ceramic balls in the core from falling off, it is necessary to keep the position of the small balls evenly distributed during mounting. When grinding, the balls can be ground uniformly. As long as the grinding does not exceed the radius of the ball, the ball can be prevented from coming out.

Metal powder refers to a group of metal particles with a size of less than 1 mm. It includes single metal powder, alloy powder and some refractory compound powder with metallic properties, and is the main raw material of powder metallurgy. Metal monomers are generally silvery-white, and when the metal is under certain conditions, it is a black powder. Most of the metal powder is black. The preparation method of metal powder is usually divided into mechanical method and physical chemical method according to the principle of transformation. It can be directly refined from solid, liquid and gaseous metals, and can be transformed from metal compounds in different states through reduction, pyrolysis and electrolysis. Carbides, nitrides, borides and silicides of refractory metals can generally be prepared directly by compounding or reduction-compounding methods. The shape, structure and particle size characteristics of the same powder often vary greatly due to different manufacturing methods. The most widely used methods of powder production are reduction, atomization and electrolysis. Metal powders are widely used in products such as powder metallurgy, 3D printing, solid fuels, audio cassettes, explosives, fireworks, pigments, batteries and catalysis. Mounting The piles of metal powder contain a lot of voids, and it is difficult to infiltrate the resin into the bottom of the powder layer under normal pressure, especially when the stacked powder layer is thick, due to the air pressure, the resin is even more difficult to penetrate. Therefore, in order to ensure that each powder can be well encapsulated by epoxy resin, vacuum impregnation is recommended to minimize the pressure of the gap between the powders, so that the epoxy resin can flow into the gap smoothly. Spread the powder evenly on the bottom of the mold, and its thickness should not be greater than 1mm, otherwise it will increase the fluid resistance of resin infiltration. But not too thin, or it is easy to over-grind during the grinding stage. Vacuum casting with TJ2562, which has high permeability (low viscosity) and edge retention, allows the metal powder to be well encapsulated by the resin after several evacuation cycles. Grinding Since many metal powders are spherical and the proportion of powder per unit volume is relatively large, if a coarser abrasive paper is used to start grinding, the powder particles will easily fall off. Generally, grinding should be done from P2000 sandpaper, if the metal powder particles are hard phase, diamond grinding disc of P2000 should be used to start grinding. Normally grinding to P2500 is sufficient for polishing. Polishing in order to make the polishing surface flat without floating convex, should use harder woven cloth, such as SC polishing cloth with diamond polishing solution. In the subsequent polishing process, in order to remove the small scratches caused by the previous polishing and improve the brightness of the sample surface, you can use a medium-pile or short-pile polishing cloth, such as YR polishing cloth with alumina suspension and special silica suspension for fine polishing to obtain a flat and smooth surface. Trojan recommends the following grinding and polishing processes for reference: Step 1 2 3 4 Surface SiC abrasive paper/diamond grinding disc SC polishing cloth YR polishing cloth Final Red polishing cloth Grain size P2000~P2500 1μm diamond suspension 0.05 alumina suspension Silica suspension Coolant Water / / / Individual specimen load /N 23 23 21 20 Time/ s 120 180 90 60 Speed of head/rpm 80 80 80 80 Speed of disc/rpm 300 150 120 120 Direction Same Same Same Reverse The final polishing with alumina suspension should be done with reasonable control of the polishing effort and time to prevent the conductor and insulating layers of the specimen from producing large floating bumps, or by using a lint-free flat ZN polishing cloth instead. In order to simplify the polishing procedure, YR/Final Red polishing cloth can also be used to mix alumina and silica suspension for simultaneous polishing, using silica polishing parameters.
