摘要：
Mechanical properties of multilayer and multicomponent coatings were investigated in this paper. Titanium nitride/titanium carbide (TiN/TiC-n) multilayer and Ti(C,N) multicomponent coatings were prepared on the surface of AISI H13 hot work tool steel by the pulsed-DC plasma assisted chemical vapor deposition (PACVD). The microhardness, the toughness, the wear loss, and the friction coefficient were examined by Vickers hardness test and the pin-on-disk wear test. The optical microscopy was also used to examine worn surfaces and to characterize wear mechanisms. The results obtaiond show that multilayer coatings of TiN/TiC-10 have the lowest friction coefficient (as 0.2) and wear loss, the highest toughness (as 17. 7 MPa.m(1/2)) and microhardness (as 3150 VHN) among those values for multicomponent Ti(C,N) coatings and other multilayer coatings.
