How can we measure the hardness of materials
WebIn general, the mechanical properties of hard thin coatings are investigated using indentation methods. Material characteristics of hard coatings, such as elastic modulus and hardness, are evaluated by means of nanoindentation and an appropriate evaluation methodology. The most popular method used to obtain the coating properties required using … WebOnly if the value of characteristics of materials is known can you achieve more sustainable and quality products. To answer these questions one of the characteristics is hardness which can be determined by the hardness test. In this article, we will discuss the hardness test, its importance, applications, etc.
