Corrosion problems in processing and storage of titanium alloy fasteners

During the machining and production process of titanium alloy fasteners, because the closeness of the mechanical parts is not so high when the fasteners are installed, it is easy to produce certain gaps, so that there will be surface gaps between the metal gaps. Paint ingress, which makes fasteners susceptible to corrosion during production. During subsequent use, the tightness of the connection will be affected. The reason why titanium alloy materials have relatively high corrosion resistance is because of the presence of oxygen in the air. After the oxidation reaction of titanium block and oxygen, a protective film will be formed on the surface. This layer of film can effectively protect the titanium alloy inside the material from oxidation, thereby improving the corrosion resistance of the titanium alloy material. However, in the actual machining process of titanium alloy fasteners, because the environment is constantly changing, including the surrounding temperature, humidity, and the oxidation of equipment during processing, etc., it will lead to the failure of 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.
