Abstract: The paper resumes the research results of fabrication of Cr3C2-NiCr ceramic coatings by plasma spray technology, which was used to improve the service lifetime of circulating pump parts working in seawater. The investigated coating properties include porosity, microhardness, slipping adhesion on steel substrates, phase composition and corrosion wear resistance. Three coating technology parameters were investigated, including plasma forming current, spray distance and powder feeding rate. Based on the results of laboratory analysis, the ceramic coating with suitable spraying mode has been applied to two seawater circulation pump systems of Nghi Sơn Thermal Power Plant No1 and give great results after more than 1 year in use. Keywords: Air Plasma Spray; Cr3C2-NiCr coating; Circulating pump. |
