Ceramic materials are particularly hard and brittle, and may also contain pores. Due to their own characteristics, cracks and grain breakage may occur during preparation. During the grinding and polishing process, detachment becomes the main problem, and often mistaken for pores. To effectively solve the problem of detachment, in addition to selecting some fine-grained abrasives, it is crucial to choose a suitable metallographic polishing cloth.

The mechanical preparation method of using metal bonded diamond discs, hard grinding discs, and hard metallographic polishing cloth is very effective in the sample grinding preparation process. SiC sandpaper is rarely used in the preparation process of ceramic samples, as it is almost as hard as ceramics and is almost ineffective for ceramic materials. Therefore, in almost all preparation steps, diamond grinding and polishing media are used. Especially in the polishing step, the selection of metallographic polishing cloth is particularly crucial.

For ceramic materials, starting from 15 μ M to 3 μ In each polishing process of m, the metallographic polishing cloth needs to be made of hard materials, such as the UltraPad metallographic polishing cloth imported from the United States, which is made of hard, lint free fabric and can match the 15 μ M-3 μ The combination of all diamond polishing agents from M produces excellent results. Of course, if you are a person who pursues the ultimate, use 6 μ M and 3 μ When using diamond polishing agent m, a metallographic polishing cloth made of TexMet hard compressed non-woven fabric material can be selected for better results; Of course, using 3 μ When using diamond polishing agent, Nylon medium hardness nylon velvet free fabric metallographic polishing cloth can also be selected, and the effect is also good. The key lies in being skillful and convenient, adapting to local conditions, eliminating the need to spend money on what you already have, and also considering cost savings. What the metallographic editor of Chain Energy wants to say is that the preparation of ceramic material samples should choose such a hard metallographic polishing cloth. Have you chosen the right one?
