Aluminum alloy, magnesium alloy, hard steel, soft steel, ceramic coating, printed circuit board? How to use aluminum oxide polishing solution for fine grinding and polishing of metallographic samples of so many types of materials? I only know the general situation, and the final process needs to use 0.05 μ M's alumina polishing solution. But how long does it take to polish? What is the loading force N? Do you need to add water.

For beginners in metallography, they are really confused and confused about how to use alumina polishing solution for polishing, Only by properly using alumina polishing solution can the ideal surface be quickly polished! The editor of Kemai Testing will help you understand how to use aluminum oxide polishing solution to cast ideal surfaces for different materials in one article. I hope it can help you.

In the family of alumina polishing fluids, the particle size is 0.05 μ m. 0.3 μ M and 1 μ Multiple particle size models such as m, where 0.05 μ M is widely used, mainly for the final polishing process of metallographic samples, which can effectively remove small scratches and ideally reproduce the microstructure and morphology of the material.

According to the different properties of various types of materials, there are slight differences in the usage methods of alumina polishing solutions. Based on daily experimental experience, the editor has compiled specific usage methods for preparing common materials, as listed below:

The above is 0.05 μ The usage method of m alumina polishing solution for polishing different material samples is for your reference.

Kind reminder:

During the polishing process, when the relative rotation of the grinding disc exceeds 500 revolutions for rapid polishing, it is necessary to add polishing cooling lubricant or water. When adding, pay attention to the flow rate being slower and then slower to ensure that the alumina abrasive particles are not washed away from the polishing cloth by the water flow and cause waste.

For materials that are prone to oxidation, do not add water. Replacing alcohol as a cooling lubricant is a good method.
