The stern shaft of a ship is exposed to seawater for a long time, which makes it susceptible to seawater corrosion and the attachment of marine organisms. Traditional anti-corrosion coatings fail within 1-2 years, and the wear of the stern shaft leads to a decrease in propulsion efficiency. Daokedao adopts WC Ni alloy+ceramic composite cladding technology, and the surface coating of the tail shaft is resistant to seawater corrosion for 12000 hours, with a surface roughness of Ra0.2 μ m and a 60% reduction in the attachment of marine organisms. After the repair of the journal, the dimensional tolerance is ± 0.02mm, and the fitting accuracy reaches IT5 level. The ship's propulsion efficiency is improved by 2% -3%. The equipment can be operated on the dock site, equipped with large tail shaft support fixtures, and the repair cycle for the Φ 500mm tail shaft is 48 hours. After the application of a certain cargo ship, the service life of the tail shaft has been extended from 3 years to 8 years, the fuel consumption of the ship has been reduced by 2%, and the annual fuel cost has been saved by 150000 yuan.
