| 目的 研究铜合金表面镍基合金涂层的耐腐蚀性能,解决铜合金表面腐蚀损伤问题。 方法 采用超音速微粒沉积技术在黄铜表面制备镍基合金涂层,通过电化学方法和中性盐雾实验对黄铜基体及镍基合金涂层的耐腐蚀性能进行测试。 结果 涂层的腐蚀电流密度较基体降低了 34 倍。 涂层表面生成的连续且致密的氧化膜阻止了腐蚀的进一步发生,在盐雾腐蚀时间进行到 500 h 时,腐蚀速度接近于零,涂层腐蚀缓慢。 结论 超音速微粒沉积技术可以制备耐腐蚀性能优异的镍基合金涂层,并且可以显著提高黄铜的基体耐蚀性。 |

| Objective The anti-corrosion properties of nickel-based alloy coatings on the surface of copper alloy were investigated, 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 prevented 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. |
