A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

This class presents a description of each hardness testing method, along with discussions on how to choose and perform a test, how to read hardness ratings, and how to prevent common errors. Hardness ...

Discover how to evaluate and compare the surface hardness of different protective coatings using accessible DIY testing ...

To investigate materials’ mechanical properties, nanoindentation and micro-compression tests are often used. These properties of materials are interrogated using either load or displacement control, ...

When designing metal parts, it's important to specify their hardness. However, many engineers have only a shaky understanding of what hardness actually is, or how it's measured. There are good reasons ...

Hardness Testing provides a thorough overview of the most common hardness testing methods, including Rockwell, Brinell, Vickers, Knoop, rebound, and ultrasonic tests. This class presents a description ...
