Abstract
Samples for metallographic examination, i.e., examination of the microstructure of the material, are prepared by precise grinding and polishing. "During the preparation of samples for metallographic examination, mechanical wear of the material occurs. This study aims to determine, and calculate, the wear of three different materials at individual steps of the sample preparation through grinding and polishing, as well as its correlation with the type of material. For the calculation, three different samples were selected, which were simultaneously subjected under the same conditions of precision grinding in four periods, i.e., several steps on different grits of the abrasive substrate. After certain time periods, measurements were conducted at twenty-eight points on all four samples. The idea of this study was to create a calculation for a more efficient, time-precise, and safer sample preparation process, thereby improving the effectiveness of the person preparing the sample, reducing the risk of sample destruction, and minimizing human stress during the task.
