Abstract

Tantalum coatings were deposited on Ti-13Nb-13Zr alloy by filtered cathodic vacuum arc deposition in order to improve the alloy's wear and corrosion resistance under load-bearing, biomedical applications. The Ta coating exhibits an amorphous structure, which transforms into a mixture of alpha and beta phases as the substrate is heated to 300
