In the machining and production process of titanium alloy fasteners, because the degree of tightness of the mechanical parts is relatively not so high when the fasteners are installed, it is easy to produce a certain gap, so that there will be a surface between the metal gaps. Paint flows in, which makes the fasteners susceptible to corrosion during the production process. In the subsequent use process, the tightness of the connection will be affected. The high corrosion resistance of titanium alloy materials is due to the presence of oxygen in the air. After the Titanium Wing Nut and oxygen undergo an oxidation reaction, a protective film is formed on the surface. This layer of film can effectively protect the titanium alloy inside the material from being oxidized, thereby improving the corrosion resistance of the titanium alloy material. However, in the actual machining process of titanium alloy fasteners, due to the constant changes in the environment, including the temperature and humidity of the surrounding environment, and the oxidation of equipment during the processing, it will lead to titanium alloy fasteners. Corrosion is easy to occur, which is one of the problems that titanium alloy fasteners are prone to in the production process.
