Long term immersion of ship propulsion shafts in seawater makes them susceptible to corrosion and attachment by marine organisms, and traditional anti-corrosion coatings fail within 1-2 years. Daokedao adopts WC Ni alloy+ceramic composite cladding technology, and the coating is resistant to seawater corrosion for 12000 hours, with a surface roughness of Ra0.2 μ m reducing 60% of marine organism adhesion. After the repair of the shaft neck, the dimensional tolerance is ± 0.02mm, the fitting accuracy reaches IT5 level, and the pushing efficiency is improved by 2% -3%. The equipment can be operated on the dock site, equipped with large shaft support fixtures, and suitable for different tonnage ship propulsion shafts of Φ 300- Φ 1000mm. After repair, the lifespan of the propulsion shaft has been extended from 3 years to 8 years, and the fuel consumption of the ship has been reduced by 2%. It is suitable for the operation and maintenance of various types of ships such as cargo ships and fishing boats.
