SUPERFICIAL HARDNESS TESTING
A highly sensitive hardness measurement, this testing technique is useful for samples with hardness gradients at the surface. Commonly known as Rockwell hardness testing—the method used at Cadorath—whereby an intender pressed into the surface of a sample at a prescribed load can be measured. A Rockwell hardness number is then calculated from the depth of indentation or permanent deformation.
ADVANTAGES OF SUPERFICIAL HARDNESS TESTING
- The method is performed strictly on coating surfaces.
- A quick method for determining superficial hardness on metals and alloys.
- Extremely sensitive and accurate.
ORIGINS AND DEVELOPMENT
The method dates back to 1919 when Stanley Rockwell, a metallurgist in a New England ball bearing manufacturing plant, invented the technique. At the time, industries lacked a good method for measuring the hardness of ball bearings and other hardened steel parts.
Computerized testing has greatly enhanced the accuracy of superficial testing with ever more accuracy and efficiency.
