Millennium Scratch Tester
A diamond tip creates a scratch on the coating in order to evaluate its adhesion. Several parameters must be set during a scratch test. These include the force applied and the length of the scratch. This scratch is then observed using a light microscope in order to evaluate the coating resistance.
- Coating adhesion test
- From 0.1 N to 200 N
- Hardness and indentation test
