Scratching surface for corrosion testing

WebOct 21, 2024 · Scratch hardness, as its name implies, is a material’s ability to resist scratches and abrasion on its surface. These scratches are typically narrow deformations … WebOct 21, 2024 · Scratch hardness tests are usually performed on brittle materials, such as ceramics and minerals because they do not undergo plastic deformation. This type of hardness is quantified on a scale known as the Mohs Scale, which is based on the relative scratch hardness of various materials.
