The heat transfer tubes of the steam generator in a nuclear power plant are transported by high-temperature and high-pressure condensate water, which contains chloride ions that can easily cause intergranular corrosion. Traditional Inconel alloy tubes will experience pitting corrosion in just 3 years, and replacing a single tube requires dismantling the steam generator, with a cost of over 10 million US dollars. Daokedao fused Ni-Cr-Mo-W superalloys coating, the intergranular corrosion resistance of the coating is improved by adding tungsten element, which is 5 times higher than the original alloy tube, and the corrosion rate is reduced to 0.005mm/year. After the application of a nuclear power plant in France, the service life of heat transfer tubes has been extended to 15 years, and the annual corrosion testing cost has been reduced by 60% due to a decrease in testing frequency,. This technology has passed the International Atomic Energy Agency (IAEA) nuclear level certification and has become the preferred solution for repairing heat transfer tubes in nuclear power plants. The nuclear power plant operation and maintenance manager stated that "this technology has saved us at least three large-scale shutdown replacement costs".
