Indentation Hardness

Indentation hardness measurement is one of various except then this is the most widely employed and acceptable technique of hardness measurement. Various parts of machines and structures, as like: gears, rails and axles, are subjected to service requirements here high resistance to abrasion or indentation is required. Indentation hardness measurement method employs an indenter of a particular material, size and shape that is pushed against the material surface beneath specified condition of loading to make an indentation. After that the dimensions of indentation are employed to designate the hardness of the material.
