I have heard a lot about diamond peeling off of diamond coated tools, resulting in unrepeatable life. What does CVD Diamond do to prevent this problem?
This has been a serious problem with diamond coated tools. In the late 1990’s interface chemistry was identified as the important issue in adhesion of the diamond film. CVD Diamond Corporation has carefully selected the carbide chemistry it uses for substrates. It uses surface preparation technique and reactor conditions that very carefully manage the interface chemistry, resulting in a very adherent diamond film. When our diamond coated tools are worn out examination under a microscope reveals that the diamond has worn all the way through to the carbide rather than chipping or peeling off.
