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 ...

Technical ceramics are utilized in a variety of products and also for coatings of components that have to be highly wear- or temperature-resistant. They are also used in non-conductive or ...

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 ...

Skoltech researchers have presented a new simple physical model for predicting the hardness of materials based on information about the shear modulus and equations of the state of crystal structures.

Although some people may consider it to be â low tech,â using pencils to test hardness is still a method used by many coatings manufacturers and some finishing shops. The test uses special pencils ...

Yogesh Vohra, Ph.D., uses microwave-plasma chemical vapor deposition to create thin crystal films of never-before-seen materials. This effort seeks materials that approach a diamond in hardness and ...
