Summary
A silicon nitride based composite material with improved wear resistance has been designed by using high fracture resistant silicon nitride substrate and high wear resistant CVD coatings. A coating system consisting of alumina, titanium carbonitride and titanium nitride was deposited by CVD on a commercial silicon nitride substrate. Physical and mechanical properties of the composite were measured and compared to those of the substrate and coating materials. The transverse rupture strength of the composite was found to be lower than that of the silicon nitride substrate. Coating adhesion was also measured and analyzed. Improvement in wear resistance was demonstrated in a cutting tool application.
