Chemical mixer blade shaft repair: Corrosion resistance upgrade of Daokedao laser cladding vs traditional surfacing
Date:2025-11-06 14:11     Source:daokedao     Browse:45

The blade shaft of a chemical mixer works in strong acid and alkali media. The traditional welding repair of the blade shaft has poor corrosion resistance and is easily corroded and worn, resulting in decreased mixing efficiency, medium leakage, and a service life of only 1-2 years.

The Daokedao laser cladding equipment uses nickel based alloy powder with strong corrosion resistance. The corrosion rate of the cladding layer in a 50% sulfuric acid and 30% sodium hydroxide solution is only 0.002mm/a, which is 1/8 of that of the overlay layer. The coating has a density of 99.9%, no risk of leakage, and a threefold increase in wear resistance.

The service life of the repaired propeller shaft has been extended to 4-5 years, and the leakage failure rate of chemical mixers has been reduced by 95%. After adopting this technology, a certain chemical enterprise has reduced the loss of medium leakage by more than 500000 yuan per year, ensuring the safety of chemical production.
