Abstract

Bone implants made from 316 stainless steel have long-term limitations due to being susceptible to corrosion and not having antibacterial properties. This research aims to improve the performance of stainless steel 316 as a bone implant biomaterial through surface modification by deposition of thin layers based on Titanium (Ti), Diamond-Like Carbon (DLC), and silver-copper (Ag-Cu) using the Plasma Enhanced Chemical Vapor Deposition (PECVD) and Direct Current Sputtering (DC-Sputtering) methods. Deposition was carried out in three coating models: DLC/Ag-Cu, Ti/Ag-Cu, and Ti/DLC/Ti/Ag-Cu. Characterization was carried out using X-Ray Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive X-ray Spectroscopy (SEM-EDX), Micro Vickers hardness test, Water Contact Angle (WCA) test, and antibacterial test. The results show that thin layer deposition of DLC/Ag-Cu, Ti/Ag-Cu, and Ti/DLC/Ti/Ag-Cu was successfully carried out with thicknesses of 2.44 μm, 1.66 μm, and 3.13 μm, respectively. Micro Vickers hardness testing shows that the Ti/DLC/Ti/Ag-Cu sample has an optimum hardness value of 198.92 VHN, which meets ASTM F319 bone implant standards. WCA testing showed that the Ti/Ag-Cu sample had the best hydrophobic properties with a contact angle of 138.15° and a surface energy of 3.95 dyne/cm, which supported the reduction of bacterial adhesion. The antibacterial test results showed that the DLC/Ag-Cu and Ti/DLC/Ti/Ag-Cu layers were able to form an inhibition zone of ±0.3–0.5 mm against Staphylococcus aureus bacteria. The results of this research show that deposition of a thin layer of Ti/DLC/Ti/Ag-Cu on stainless steel 316 provides the best performance with increased hardness, increased contact angle, and provides antibacterial coating performance.
