Due to working in rivers and marine environment for many years, a large number of parts and components of drilling platform ships, large ship cranes and other mechanical equipment will be corroded and worn, and need to be protected and repaired. For the preparation of large-area wear-resistant and corrosion-resistant coatings on the surface of shaft parts, efficient surface processing technology is required; In case of local wear failure of some power equipment, such as iron filings and impurities in the lubricating oil system, the influence of low oil temperature or oil pressure during the unit startup is easy to cause wear of bearing bush and shaft diameter, which requires cladding and repair in local areas, so it is suitable to adopt the robot automatic repair method with better flexibility.
In view of the wear and corrosion of marine machinery parts, laser cladding repair and remanufacturing technology can meet the application needs of the above situation at the same time, and has been widely used in marine diesel engines, marine gas turbines, steam turbines, propellers and ship hulls.
