Abstract

In the present investigation, Ti+TiN+TiAlN-MoS2+MoS2-Ti solid multilayer-composite solid lubricant coating was deposited by magnetron sputtering from separate Ti, Al, and MoS2 target on D2 tool steel. EDS, X-ray diffraction, microhardness tester, scratch tester, and pin-on-disc tribo system were used to evaluate coating structural, mechanical and tribological properties. Adhesion was also improved in the multilayer-composite coating. Pin-on-disc measurement at atmospheric condition against WC ball showed much lower wear and friction coefficient.
