Problems solved by technology
[0003] During the metallographic test of stainless steel, the level of sample polishing directly determines the level of metallographic structure inspection. Because the hardness of stainless steel is high, there is a large gap between the hardness of the stainless steel material and the inlaid resin material, and the degree of wear of the two during the polishing process is often difficult. Consistent, it is not easy to grind flat, and the joint between stainless steel and inlaid materials is easy to produce gaps. During the polishing process, these gaps are easy to accommodate polishing paste. When the subsequent corrosion process is performed, the polishing paste precipitates and affects the corrosion effect.
At present, metallographic polishing pastes are mostly products made of cerium oxide and chromium oxide as polishing powder mixed with other raw materials. They are mostly yellow, which can easily cause staining on the test surface. At the same time, these polishing pastes must ensure stability and uniformity. The paste is often viscous and difficult to disperse, and it is difficult to effectively disperse it on the polishing cloth during the polishing process, resulting in great waste
There are also polishing pastes using diamond powder as polishing powder, but the price is extremely expensive

Description
technical field [0001] The invention relates to a polishing paste, in particular to a stainless steel polishing paste and a preparation method and application method thereof. Background technique [0002] Metallographic inspection of stainless steel is the most direct test method to test the heat treatment state of stainless steel materials. In all quality control processes of stainless steel manufacturing and processing, metallographic analysis is an indispensable and important part. The main test content of metallographic analysis includes testing grain size, grain shape, carbide determination and distribution, etc. In addition, metallographic analysis is also one of the commonly used methods in the failure analysis process of studying the mechanism of corrosion and oxidation. The pretreatment process of metallographic analysis is complicated, and the samples for metallographic analysis have a great influence on the results of metallographic analysis, and a lot of experien...
