N2 - Bone implants are a tool that is often used in the medical world. The function of the bone-implant itself is as a reinforcement, anchor, and connecting human bones that are damaged. SS 316L stainless steel is a metal material that is often used for bone implants, because it has good mechanical properties, a low corrosion rate, and is easily fabricated. In this study, the test specimen was in the form of ST-41 steel coated with Titanium Nitride (TiN) material with a PYO Coating method as an alternative material from SS 316L stainless steel type. The test specimen was immersed in a corrosive solution in the form of Simulated Body Fluid (SBF)) i.e. artificial blood solution with chemical content close to the actual human blood with soaking variations of 12 hours, 168 hours, 240 hours and 336 hours. Tests conducted in this study include Potentiodynamic Polarization (POP) and Electrochemical Impedance Spectroscopy (EIS). The results obtained with the lowest corrosion rate on ST-41 steel material coated with TiN of 0.00092597mm/year at 12-hour immersion and the highest corrosion rate of 0.014261mm/year at 168-hour immersion. While the corrosion rate on SS 316L material obtained the lowest corrosion rate of 0.0013166mm/year at 336 hours immersion and the highest corrosion rate of 0.0052665mm/year at 168 hours immersion.
