Study on Anti-corrosion Property of Nickel-based Alloy Coatings on Copper Surface Formed by Supersonic Particle Deposition
摘要
Abstract
ABSTRACT:Objective The anti-corrosion properties of nickel-based alloy coatings on the surface of copper alloy were investiga-ted, and damages caused by corrosion on the copper surface were resolved. Methods Nickel-based alloy coatings were prepared on the surface of brass by supersonic particle deposition, and the anti-corrosion properties of brass substrate and nickel-based alloy coating were tested by electrochemical technology and neutral salt spray test. Results The corrosion current detensity of the coating decreased 34 times compared to that of the matrix. The successive and pyknotic oxide film formed on the surface of the coating pre-vented further occurrence of corrosion. When the salt spray corrosion time reached 500 h, the corrosion rate was close to 0 and the corrosion of the coating was slow. Conclusion Supersonic particle deposition technology could be used to prepare nickel-based alloy coatings, which could significantly improve the corrosion resistance of the brass substrate.关键词
