摘 要：TiNi alloy has a high resistance to wear and could be an excellent candidate for various tribological applications. But studies show that oxygen active elements can improve properties of some alloys,markedly.Yttrium is one of the oxygen active elements.In this paper,the e-ects of yttria addition on properties of TiNi have been studied via micro-indentation,hardness,wear and corrosive wear tests.It is demonstrated that by addition of yttria to 5%,TiNi alloy can own improved mechanical properties and resistance to wear and corrosive wear.
