Description

technical field [0001] The invention belongs to the technical field of surface engineering, and in particular relates to a low-stress, high wear-resistant and erosion-resistant coating, a preparation method and an application. Background technique [0002] Due to the excellent characteristics of high specific strength and low density, titanium alloys have been widely used in various fields, especially the aerospace industry. However, due to the disadvantages of titanium alloys such as poor wear resistance, low hardness, and poor ductility, the application range of titanium alloys is limited. Surface modification of titanium alloy can greatly improve the surface properties of titanium alloy, endow it with new physical properties, and expand its application range. [0003] Due to the special surface characteristics of titanium alloy, the traditional surface treatment process: chemical chrome plating, chemical nickel plating and other surface coating processes can improve its ...
