Sample Preparation Before Micro Vickers Hardness Testing In most cases, samples are sectioned and mounted prior to micro Vickers hardness testing. The samples are then ground, sanded and polished to provide a test surface free of scratches and surface texture. Sometimes production demands do not ... Read More

Common Problems in Microhardness Testing Microhardness testers are delicate instruments. Extremely light forces (typically from 10 to 1,000 g.) must be accurately applied, and the resultant impressions (some as small as 10 microns) must be precisely measured under high magnification. And so there ... Read More
