Abstract

316L Stainless steel (SS 316L) is a metal material that has superior corrosion resistance properties, so this material is widely used in medical, manufacturing, nuclear, food, etc.  However, this metal can still be damaged or scratched due to weaknesses in hardness and wear resistance. This research was carried out to overcome these shortcomings by using Diamond Like Carbon (DLC) coating which can improve the hardness and wear resistance of SS 316L. DLC coating was done using the glow discharge plasma technique at  temperature of 400°C and  pressure of 1.6 mbar for 4 hours with variety of argon (Ar) and LPG gas mixtures. The results of DLC coating optimum conditions were obtained at the gas mixture ratio of 80% Ar and 20% LPG with the increase of hardness from 157.9 VHN to 329.84 VHN, and wear resistance  decreased from 1.0176×10-3 mm3/kg.mm to 0.7×10-3 mm3/kg.mm. The improvement in the properties of this treatment was proven by SEM EDS which showed the formation of 69% graphite phase (G) and 31% diamond phase (D), as well as from Raman spectroscopy analysis, sp3 and sp2 bonds were obtained.
