The corrosion and wear resistance is of great importance for biometals in terms of biocompatibility
and biomechanical interaction within the human body. Due to the nature of metals, their active
structures cause their biodegradation within a certain period of time. Body fluids produced by living
organism create highly effective corrosive damage on metallic surfaces. In addition, metallic
surfaces that can be worn mechanically spread in the form of particles in the body, creating a toxic
effect. These problems can be overcome by accumulating passive films on the surface of metallic
implants. There are many studies related to different methods in the literature for the production of
these films. One of these methods is electrophoretic deposition (EPD). The coatings made using the
electrophoretic deposition method play a role in increasing wear and corrosion resistance, especially
for implants used in the biomedical field. By producing ceramic-derived coatings, non-bioactive
structures can be obtained by applying them on metallic biomaterials. Corrosion and wear resistance
of the metal-based implant material is increased with thin films containing metal oxides, nitrides,
borides and similar nonmetallic structures. Osseointegration can be improved by covering spinal
implants, bone plates and screws with EPD used in the field of orthopedics. In addition, high tribocorrosion resistance can be developed, which is a very important feature for most implant groups. In
this study, it was coated with 316L stainless steel used in the field of orthopedics by using the
hexagonal boron nitride (h-BN) EPD method, which does not show any biodegradable properties,
and the tribocorrosion resistance is increased. For this purpose; 316L base material is coated with
solutions prepared at different concentrations, and the resistance of tribocorrosion in the simulated
body fluid was investigated. Tribocorrosion process was carried out under 2 N load and was
completed with open circuit potential (OCP) and potentiodynamic polarization scan. Maximum
performance is obtained in thin film produced with optimum coating conditions.
