    • A method for surface treating a titanium gas turbine engine component. The method includes providing a gas turbine engine component having a titanium-containing surface. The component is heated to a temperature sufficient to diffuse carbon into the titanium and below 1,000° F. The surface is contacted with a carbon-containing gas to diffuse carbon into the surface to form carbides. Thereafter, the carbide-containing surface is coated with a lubricant comprising a binder and a friction modifier. The binder preferably including titanium oxide and the friction modifier preferably including tungsten disulfide. The coefficient of friction between the surface and another titanium-containing surface is less than about 0.6 in high altitude atmospheres.
    • 一种表面处理钛燃气涡轮发动机部件的方法。 该方法包括提供具有含钛表面的燃气涡轮发动机部件。 将组分加热到足以将碳扩散到钛中并低于1000°F的温度。表面与含碳气体接触以将碳扩散到表面中以形成碳化物。 此后,含有碳化物的表面涂覆有包含粘合剂和摩擦改进剂的润滑剂。 粘合剂优选包括氧化钛和摩擦改进剂,优选包括二硫化钨。 表面与另一含钛表面之间的摩擦系数在高海拔环境中小于约0.6。
