“The system would be used for measuring microscopic hardness in micro Vickers of metals/alloys, various phases/micro-constituents present in metal matrix, thin wires & sheets, diffusion coatings and case depth of carburised/ nitride components etc.

Features:

A low cost upto-mechanical instrument which can be used for measuring microscopic hardness in micro Vickers. The instrument comprises of a microscope with a filar micrometer eye piece mounted on a stand, loading and unloading mechanism attached to the microscope for taking an indentation of a diamond indenter on a specimen surface under certain load in gms, an illumination system mounted on the microscope and rotating table having X and Y movements.
