Abstract
Fatigue test is a requisite for the application of titanium and titanium alloys as a dental casting material in addition to tensile test, hardness test, and others. It is considered that corrosion fatigue test is important because dental prosthesis is generally used in the oral cavity. In this study, corrosion fatigue property in 0.9% NaCl solution using corrosion fatigue test equipment of Ti-6Al-4V alloy and Ti-6Al-7Nb alloy dental castings was investigated. As a result, the corrosion fatigue property of Ti-6Al-7Nb alloy castings was good, and that it is practical for use as a dental material.
