Friction testing using diamond pushes material analysis to the extreme Because diamond is one of the hardest known materials, it’s used to measure friction, wear, and surface durability with exceptional accuracy. As a diamond tip slides across a surface under controlled load, engineers can study resistance, deformation, and failure at microscopic levels. This t
