Titanium alloy flexible package wear-resistant coating and preparation method thereof

The invention discloses a titanium alloy flexible package wear-resistant coating and a preparation method thereof, and solves the problem of wear resistance of a titanium alloy. The components of the coating are primary Si and (alpha+Si) eutectic structures, and the component of the coating-matrix bonding interface structure is a Ti-Al intermetallic compound. The coating has good wear resistance, the hardness from the surface of the coating to a matrix shows the characteristic of flexible package, the hardness of the coating part is lower than that of the titanium alloy matrix, but the wear resistance of the coating part is greatly improved compared with that of the titanium alloy matrix. The coating is prepared through a plasma welding and synchronous powder feeding cladding technology, the technological method is easy to implement, the technological process can be controlled, and the technological forming quality is high. 本发明公开了一种钛合金软包装耐磨涂层及其制备方法，解决钛合金的耐磨性问题。该涂层的成分为初生Si和（α+Si）共晶组织，涂层-基体结合界面组织成分为Ti-Al系金属间化合物
