Indentation Hardness

Indentation hardness measurement is one of several but this is the most widely used and acceptable method of hardness measurement. Several parts of machines and structures, such as gears, axles and rails, are subjected to service requirements where high resistance to indentation or abrasion is required. Indentation hardness measurement method uses an indenter of a specified material, shape and size which is pushed against the material surface under specified condition of loading to create an indentation. Then the dimensions of indentation are used to designate the hardness of the material.
