Synergistic Regulation Mechanism of Inorganic Thermal Oxidation Coating and Poly (Vinylphosphonic Acid) (PVPA) Coating for High Load Bearing Superlubricity

A low friction coefficient and high bearing capacity can improve the service life of implants in human body. In this study, we firstly investigate mechanical properties inorganic thermal oxide coatings on titanium alloy (Ti6Al4V). Tribological experiments were performed for different tribo-pairs under uniform conditions. The coating Ti6Al4V formed at 300℃ was found to have excellent tribological effectively Ti6Al4V. organic poly (vinylphosphonic acid) (PVPA) has anti-friction properties, which help achieve superlubricity. An oxide/organic PVPA composite fabricated obtain a surface with capacity. It is that presence doubled compared alone. This study serve as guide modification artificial joints.
