MICRO HARDNESS TESTING
Micro hardness testing is used to measure the hardness of materials on a microscopic scale. At Cadorath, indentations are made on the surface of specimens with a diamond indenter and the size of the indentation is then calculated with an optical microscope. The material is evaluated for hardness by measuring the stress necessary to make the indentation.
ADVANTAGES OF MICRO HARDNESS TESTING
- Excellent for determining relative micro hardnesses.
- Can be applied to a large variety of metal alloys and other materials.
- Readings are taken solely from the applied coatings, removing the possibility of errors.
ORIGINS AND DEVELOPMENT
Some of the earliest forms of hardness testing include bar scratch testing, dating back to the early 1700s. A century later, testing methods were introduced that included scratching and measuring material surfaces with diamond bits.
Originally used for very small components, micro hardness testing has extended to include metallic and ceramic materials of all sizes and descriptions. With the advent of computers, testing techniques and hardware have significantly improved in both scope and accuracy.
