How a Vickers Hardness Tester Works
Vickers Indentation Testing Principle
The tester measures hardness by creating a small indentation using a diamond pyramid indenter.
Diamond Pyramid Indenter Process
A controlled load is applied to the material surface for a specified period.
Reading and Calculating Hardness Values
Hardness values are calculated based on indentation diagonal measurements.
