In the process of machining Titanium Flat Washers, because the tightness of the mechanical parts is not so high when the fasteners are installed, it is easy to generate a certain gap, so that there will be a surface between the metal gaps. Paint flows in, making fasteners susceptible to corrosion during production. In the subsequent use process, the connection tightness will be affected. The reason why titanium alloy materials have high corrosion resistance is because of the presence of oxygen in the air. A protective film is formed on the surface of the titanium alloy material after the oxidation reaction with oxygen. 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 influence of factors such as ambient temperature, humidity, and equipment oxidation during processing, it will lead to titanium alloy fasteners. Corrosion is easy to occur, which is one of the problems that are prone to occur in the production process of titanium alloy fasteners.
