Abstract
Diamond like carbon coatings have excellent wear properties with high hardness. The hardness and adhesion properties vary with sp3/sp2 ratio and coating thickness. In this research, effect of coating thickness on stainless steel substrate has studied. Diamond like carbon coatings of 300nm, 500nm, and 650nm has deposited using Filter Cathodic Vacuum Arc System with Magnetron sputtered Chromium interlayer. The characterization includes, Field Emission Electron Microscopy, Raman spectroscopy, Tribology and Adhesion strength evaluation. It was concluded that, surface finish decreased with increase in coating thickness. Maximum ID/IG of 0.84 was obtained for 30nm diamond like carbon coated stainless steel. The minimum average friction coefficient of 0.115 was obtained for 500nm coating. Moreover, it was observed that, friction coefficient decrease with increase in coating thickness in initial phases, after certain time it increase directly proportional to thickness. For adhesion strength, LC1 was found good for 650nm and LC2 for 500nm respectively.
