Magnesium and its alloys are getting attraction in automotive industry due to its attractive density and strength. It is also researched for bio implants due to its bio- compatibility. But it has poor wear resistance and corrosion resistance. Hence the current work is aimed at coating the magnesium alloy composites with DLC (diamond-like coating), a recent addition in surface engineering has been showing impressive properties high hardness, chemical inertness, wear resistance and low coefficient of friction in addition to bio- compatibility. In this research a magnesium nano-composite reinforced with TIO2has been coated with DLC (diamond-like carbon) by using RF Sputtering process. The results of this coating are showing great potential in achieving uniform coatings and improved surface hardness of more than 40%. In this report, the process of DLC coating process and the surface morphology along with improvement microhardness are discussed with details. Coated surface is characterized using Raman Spectroscopy. © 2017 Elsevier Ltd.
