Research 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. A new equipment that makes corrosion environment was produced for corrosion fatigue test. In this study, corrosion fatigue property in 0.9 % NaCl solution using corrosion fatigue test equipment of Titanium, Ti-6Al-4V alloy, Ti-6Al-7Nb alloy and Ti-5Al-13Ta alloy dental castings was investigated. As a result, the corrosion fatigue property of Titanium, Ti-6Al-7Nb alloy, Ti-5Al-13Ta alloy castings was good, and that they are practical for use as a dental material.
