In the present investigation, TiN/TiAlN-MoS2/MoS2-Ti multilayer-composite solid lubricant coatings were deposited by magnetron sputtering from separate Ti, Al, and MoS2 targets on D2 tool steel. EDS, X-ray diffraction, microhardness tester, scratch tester, and pin-on-disc tribo system were used to evaluate structural, mechanical and tribological properties of the coating. Pin-on-disc measurements at atmospheric condition against WC ball showed lower wear and friction coefficients. No evidence of interfacial failure(s) of the sub-layers was observed in the adhesion and tribo-wear tests. |
