摘　　要：无氰碱性镀锌在民用领域应用广泛,由于其缺乏系统性的全面考核评价,目前尚未进入航空标准件生产企业替代氰化镀锌工艺。为此研究了无氰碱性镀锌和氰化镀锌镀液的均镀能力、深镀能力,以及镀层腐蚀电位、耐蚀性、氢脆性等镀层性能。经试验对比表明,无氰碱性镀锌能满足航空标准件的一般要求。Cyanide-free alkaline zinc plating has been widely used in civilian areas. However,it has not been used in the aviation standard parts production due to the lack of systemic comprehensive evaluation.Therefore,the throwing power and coving power of cyanide-free alkaline and cyanide zinc plating solution were compared,and the coating properties such as corrosion potential,corrosion resistance,and hydrogen brittleness were analyzed and studied. The comparison tests showed that the cyanide-free zinc plating could meet the general requirements of aviation standard parts.
