摘　　要：为了提高碳钢在海水中的耐蚀性,在碳钢表面电沉积Ni-Co-ZrO_(2)纳米复合镀层,利用Autolab电化学工作站测试镀层在模拟海水中的电化学性能,研究超声功率、电流密度及纳米粒子质量浓度等工艺参数对复合镀层电化学腐蚀行为的影响规律。结果表明,碳钢镀覆Ni-Co-ZrO_(2)纳米复合镀层在模拟海水中具有更为优良的耐蚀性能,电沉积的优化工艺条件为:超声功率120 W、电流密度6 A/dm^(2)、纳米粒子质量浓度1 g/L。In order to improve the corrosion resistance of carbon steel in seawater,Ni-Co-ZrO_(2)nanocomposite coatings were electrodeposited on the surface of a carbon steel.The electrochemical performance of the coat-ings in simulated seawater was tested by Autolab electrochemical workstation.The influences of process pa-rameters such as ultrasonic power,current density,and nanoparticle concentration on the electrochemical cor-rosion behavior of the composite coatings were studied.The results show that the Ni-Co-ZrO_(2)nanocomposite coating on carbon steel exhibits better corrosion resistance in simulated seawater.The optimized process condi-tions of electrodeposition are as follows:ultrasonic power 120 W,current density 6 A/dm^(2),and nanoparticle concentration 1 g/L.
