The impeller of the seawater aquaculture aerator is immersed in seawater containing plankton for a long time, and shellfish and algae are prone to adhere to the surface and form biofilms, resulting in a 30% decrease in impeller head. Traditional cast iron impellers, without anti-corrosion treatment, will rust and be scrapped within one year. Daokedao fused Ni Cu Zn ternary alloy coating, by adjusting the alloy ratio, the surface tension of the coating was reduced, the biological adhesion rate was reduced by 60%, the surface smoothness was improved by 40%, and the salt spray corrosion resistance reached 6000 hours. After being applied by a large aquaculture company in Norway, the cleaning cycle of the impeller was extended from 1 month to 6 months, and the lifespan was extended from 1 year to 5 years. The oxygenation efficiency remained stable at over 90%, avoiding the increase in fish and shrimp mortality caused by insufficient oxygen supply. The cost of replacing impellers during the annual festival is 250000 US dollars. The director of aquaculture stated that "after the equipment was put into use, the survival rate of fish and shrimp increased by 8%, and the indirect benefits far exceeded the equipment investment".
