A METHOD FOR NANO-PARTICLE REINFORCED COATINGS FOR SECONDARY PIPING SYSTEM OF NUCLEAR POWER PLANT

摘要

According to the present invention, a coating method using a nanoparticle for inhibiting fluid accelerated corrosion in a secondary piping system of a nuclear power plant comprises the steps of: (a) adding TiO_2 and SiC to a nickel plating solution; and (b) forming a complex coating layer of Ni-TiO_2 and Ni-SiC on the top of the surface of carbon steel. The method is effective in inhibiting corrosion of a material by coating an internal diameter of a pipe by using a nanoparticle, and significantly improving stability and reliability of a second side of a nuclear power plant by reducing fluid accelerated corrosion.
