Daokedao Laser Cladding for Marine Propeller Repair: Enhancing Corrosion Resistance
Marine propellers work in seawater for a long time, and are prone to corrosion, cavitation and wear, which affects the ship's navigation speed and fuel efficiency. Traditional propeller repair methods have poor corrosion resistance and short service life. Daokedao's laser cladding equipment provides a high-quality repair solution for marine propellers. The equipment uses marine-grade corrosion-resistant alloy powder (such as nickel-chromium-molybdenum alloy) to clad the damaged part of the propeller. The clad coating has excellent seawater corrosion resistance and cavitation resistance, which can effectively isolate the propeller from seawater and extend its service life by 3-4 times. The equipment's flexible cladding head can adapt to the complex curved surface of the propeller, realizing precise cladding of each blade. The cladding process has a small heat-affected zone, which will not cause deformation of the propeller, ensuring the dynamic balance of the propeller. Daokedao has provided propeller repair solutions for many shipping companies in Greece, Norway and other maritime countries. The repaired propellers have passed the marine inspection of the classification society, and the navigation performance is the same as that of new propellers. The repair cost is only 30% of the cost of replacing a new propeller, saving a lot of costs for shipping companies.
