Ship stern shaft repair

Today, we will introduce the application of high-speed arc spraying in the repair of ship stern shafts. For the repair of ship engine shaft parts, iron plating, brush plating, dimensional repair, thermal spraying, surfacing and other process methods can be used. However, for ship tail shafts, due to the large size and repair area, currently, for different tail shaft structures and wear Depending on the situation, bare car repair, thermal spraying, surfacing or copper inlay processes are mainly used. In recent years, with the continuous development of thermal spraying process methods, spraying materials and the continuous improvement of coating performance, the application of thermal spraying technology in the repair and remanufacturing of marine engine parts is continuously expanding.
However, high-speed arc spraying technology is a mechanical parts repair technology. It uses the heat source generated by the arc to atomize the molten metal wire with an air flow through a special nozzle, and spray it onto the surface of the parent body at high speed to form a This kind of coating plays a strengthening and repairing role to improve the wear resistance and corrosion protection of parts. Because of its characteristics of economy, speed, high efficiency, and reliable technology, it can be used in the repair of ship stern shaft repair and other parts.
