The influence of ultrasonic vibration frequency on the properties of TiN coated biomedical Ti-13Zr-13Nb

Bare biomedical grade titanium alloys are prone to degradation when in a body fluid environment. Surface coatings such as Physical Vapor Deposition (PVD) can serve as one of the options to minimize this issue. Past reports showed that the PVD coated layer consists of pores, pinholes, and columnar gr...
