Resum
The contact fatigue behavior of a fine-grained hardmetal coated with two distinct ceramic films, either a TiN monolayer or a WC/C multilayer, is studied by means of indentation testing techniques. Spherical indentation tests indicate that the investigated coated systems exhibit different susceptibility to fatigue degradation in terms of emergence of circular cracks at the coating surface. Furthermore, these cracks are found to induce well-defined substrate cracking without any intermediate decoh...
