镍基氧化铝对舰船用材料防腐性能研究

Research on nickel-based alumina of ship materials on anti-corrosion performance

镍基合金大多具有良好的耐腐蚀性,氧化铝的纳米级颗粒可以和镍基电镀液一起,形成具有抗腐蚀性、耐磨性强的电镀材料。本文以瓦特镀镍溶液为基础电镀液,加入纳米氧化铝,通过共沉积的方法,制得镍基纳米氧化铝电镀液,通过对经过电镀涂层的舰船用材料浸泡试验和极化曲线测试,测试数据表明,镍基氧化铝涂层可以提高舰船用材料的防腐蚀性能。

Most of the nickel-based alloys have good corrosion resistance, and the nanometer particles of alumina can be combined with the nickel base plating solution to form electroplating materials with high corrosion resistance and high wear resistance. In this paper, adding nano alumina to basis nickel electroplating solution, via co-deposition to prepare Ni base alumina coating. Through the immersion test and polarization curve test of the plating coating ship, the test data show that the Ni-based alumina coating can improve the corrosion resistance of the ship material.
