Abstract: Titanium and its alloys have found application in biomedical fields primarily because of their sterling mechanical characteristics and bio-compatibility. But they can corrode when in contact with body fluids thereby being a limitation to their longevity. This is why surface modification techniques play a crucial role in strengthening the protection of the material and rendering it corrosion resistant. In this study, composite of HA/PCL/Gelatin was successfully deposited on Ti6Al4V substrate by dip coating technique. Microscopic analysis showed that the 70% PCL coating resulted in a smoother and more uniform surface compared to the 30% PCL coating. Rockwell C hardness testing confirmed that the Ti-6Al-4V substrate had a hardness of 35 HRC. Scotch tape adhesion tests indicated superior bonding strength for the 70% PCL coating, with minimal coating removal. In Ringer's solution, the 70% PCL coating exhibited only 11% degradation over three weeks, while the 30% PCL coating showed 29% degradation. These results demonstrated that higher PCL content significantly enhances coating adhesion and corrosion resistance, suggesting improved long-term stability and performance of Ti implants.
