Friends who work in metallography have a consensus that during the metallographic inspection process, magnesium alloy materials have a low matrix hardness and a high precipitation phase hardness, making it difficult to prepare samples and the phenomenon of floatation is easy to occur. To solve the problem of protrusion, in addition to reducing polishing time or using diamond polishing paste instead of polishing liquid, using short plush metallographic polishing cloth for polishing is a quite effective method. Therefore, if the use of polishing paste and measures to reduce polishing time still result in protrusion, then please change to a metallographic polishing cloth.
Based on personal work experience, Chaineng Metallographic Editor suggests using high-quality ChemoMet metallographic polishing cloth imported from QMAXIS from the United States for polishing steps in the preparation of magnesium and magnesium alloy samples. This will effectively solve the problem and make the preparation of magnesium alloy samples much easier.

This metallographic polishing cloth is ChemoMet, originally imported from the United States, with a porous fiber structure that can effectively hold abrasive media particles; Good chemical resistance, soft short pile synthetic fabric. These characteristics make the surface of this metallographic polishing cloth softer, and the abrasive can penetrate into the interior of the fluff. Compared to hard metallographic polishing cloth, although the removal rate is relatively small, it can greatly avoid the generation of protrusions, ensuring better sample surface quality. In addition, this ChemoMet high-quality metallographic polishing cloth does not shed fibers, does not stain, and does not cause pollution or secondary damage to the surface of the sample, ensuring that the true microstructure of the material is not damaged. Whether we use it for quality control or research, it is very suitable. Therefore, with this metallographic polishing cloth, the preparation of magnesium and magnesium alloy samples is much easier.
This is the ChemoMet metallographic polishing cloth, a soft, porous, chemical resistant velvet cloth, black, which can be used with 1 μ M~0.02 μ M's diamond, alumina, or silicone polishing agents are used together. Not only suitable for fine polishing of magnesium and magnesium alloy samples, but also suitable for polishing of titanium alloys, stainless steel, lead/tin materials, solder, electronic packaging, and soft non-ferrous metals and plastics. If your sample happens to be one of these materials and the prepared surface is always not ideal, you may want to try this ChemoMet metallographic polishing cloth and see if it can be improved. If you encounter any problems in the application, you can always contact the engineers of Chain Metallography for assistance.
