Abstract

A new surface-coating method by which CaP invert glass is used to improve the bioactivity of titanium alloys has been developed recently. In this method, the powder of CaP invert glass (CaO-P₂O₅-TiO ₂-Na₂O) is coated on the surface of titanium alloy samples and heated between 1073 and 1123K. With this treatment, a calcium phosphate layer mainly containing β-Ca₃(PO₄) ₂ phase can be coated easily on titanium alloy samples. In the present study, the effect of this coating process on the fatigue properties of Ti-29Nb-13Ta-4.6Zr, a new metastable β alloy for biomedical applications, has been investigated. The fatigue endurance limit of the coated alloy was found to be about 15% higher than that of uncoated alloy, as a result of the formation of a hard (α+β) layer and a small amount of the ω phase during the coating process. The coating exhibits excellent adhesion to the substrate during the tensile and fatigue tests. Subsequent ageing at 673K for 259.2ks greatly improves the fatigue resistance of the coated alloy due to isothermal ω phase precipitation, and does not have obvious detrimental effect on the coating properties.
