Corrosion Resistance of Ni-CeO2 Nanocomposite Coatings Prepared by Pulse Electrodeposition in an Ultrasonic Field
Source abstract
Abstract
在超声场中用脉冲电沉积法制备了Ni-CeO 2 纳米复合镀层, 考察了镀层中CeO 2 含量及表面形貌,研究了镀层在10wt%HCl溶液中的耐蚀性, 分析了超声作用下脉冲参数对镀层耐蚀性的影响. 结果表明：脉冲参数和超声波对镀层中CeO 2 含量和微观组织均有影响, 适宜的脉冲参数可以提高镀层中CeO 2 含量,细化镀层晶粒, 而超声波可促使镀层晶粒进一步细化; Ni-CeO 2 纳米复合镀层的耐蚀性与镀层中CeO 2 含量、镀层晶粒大小及组织致密程度有关; 在占空比0.2、脉冲频率1000Hz时超声作用下制备的镀层中CeO 2 含量较高, 镀层晶粒细小、组织致密, 腐蚀速率最低, 表现出优良的耐蚀性.
