Diamond Penetrator Hardness Testings (Vickers) |
The test operation is basically
the same as the Brinell Hardness
Testing but with a different penetrator. Instead of a
bullet an obtuse equilateral diamond pyramid is pressed into
the workpiece.
The hardness is calculated with the diameter
(d) of the pyramid's impression:
HV = 0,102 x F/A = 0,189 x F/d²
d = d1 + d2 / 2
Advantages and Disadvantages
All-purpose hardness testing – only for medium-hard
and hard metals.
Applicable for:
Hardened steel, hardened surfaces, parts of a microstructure
