成分接近等原子比的钛镍合金具有优良的形状记忆特性和超弹性,而且耐环境腐蚀性也很优越,但是在海洋、生体以及化学装置上使用时往往由于少量氢的侵入而引起某些性能,特别是反复变形特性的劣化。为了改善钛镍合金的抗吸氢性能,已开发了加铜的钛镍铜三元合金以及氮离子注入...
Titanium-nickel alloys with similar atomic composition have excellent shape memory properties and superelastic properties, as well as excellent resistance to environmental corrosions, but some properties are often caused by the intrusion of a small amount of hydrogen when used on marine, biological and chemical devices In particular, the deterioration of the repeated deformation characteristics. In order to improve the anti-hydrogen absorption properties of titanium-nickel alloy, copper-added titanium nickel copper ternary alloy and nitrogen ion implantation have been developed.
