Portable Hardness Testing for Effective Quality Control: Techniques and Applications
The purpose of hardness testing is to ascertain a material's strength, heat treatment, and wear properties. It's usually carried out on metals to confirm their characteristics and fitness for specific applications. Traditionally, the test could only be conducted with a benchtop system. However, advancements in technology have led to the development of portable hardness testing methods that allow testing on different scales, depending on the applied force and indenter's shape, with Brinell and Rockwell being the most frequently used. Let’s talk about the different methods and their applications. Leeb testing technique Leeb hardness is the indenter’s relative velocity before and after impact. A portable hardness testing device that uses this testing technique will bounce the indenter off the test piece surface with a spring-loaded mechanism. One of the benefits of this system is its portability, so you can bring the device to the element instead of taking a sa
