钛合金是一种通用的结构材料,具有无磁性、高的抗腐蚀性和高的比强度等物理机械性能。目前,钛及其合金的主要使用部门是航空和宇航工业。据报道,这种金属的83％应用在音速和超音速飞机、火箭弹和宇宙飞船的各种结构部件上。 然而,未经强化处理的钛及其合金的抗摩性质都很差,钛对钛或其他金属的干摩擦系数高达0.48～0.68,这就严重地限制了它们的实际应用。为了提高钛合金的抗摩性质,人们已制定了以下三类可行的方法:
Titanium alloy is a common structural material, with non-magnetic, high corrosion resistance and high strength and other physical and mechanical properties. Currently, the main sectors of use of titanium and its alloys are the aerospace and aerospace industries. It is reported that 83% of this metal is used on various structural components of sonic and supersonic aircraft, rockets and spacecraft. However, the untreated titanium and its alloys have poor anti-friction properties and the dry friction coefficient of titanium to titanium or other metals is as high as 0.48 to 0.68, which severely limits their practical application. In order to improve the anti-friction properties of titanium, people have developed the following three possible methods:
