Vicker Hardness testing Machine

The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness. The Vickers test can be used for all metals and has one of the widest scales among hardness tests.** The Vicker hardness testing machine in lab was made in Japan.

The Vickers hardness test was developed in 1924 by Smith and Sandland. Following components used in Vicker hardness testing machine;

Indenter:

Highly polished pointed square base pyramidal diamond with face angles of 136 is used in this method.

Microscope:

A microscope in conjunction with the hardness tester is used to determine the size of indentation.

Table:

Sample is placed on the table for test.

Wheels:

Different wheels are used to focus the microscope and properly place the sample.
