Common Pitfalls in Hardness Testing  Gear Solutions

Common Pitfalls in Hardness Testing Gear Solutions

Although the polishing method used for sample group 1 produces what seems to be a high quality surface finish, it leaves a significant amount of deformed metal near the surface of the component, which results in erroneous and misleading hardness testing results. Sample group 2, by contrast, displayed only marginally higher hardness values than

Common Problems in Microhardness Testing 2014 05 01

May 01, 2014By their nature, 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 are a number of problems inherent to all of them. When people think of microhardness testing, three terms often come
