前言锌钛合金镀层于六十年代初期在日本首先出现,二十多年来不断取得新的进展。由于它具有优异的抗蚀能力,因而在国际上引起了广泛注意。现在,锌钛合金电镀液已从非水溶液发展到水溶液,从氰化发展到无氰;合金镀层中钛的含量也不断提高,从而使镀层在严酷的腐蚀环境中表现出更为显著的抗蚀性能。国内也有人从碱性溶液中沉积出含钛0.5％左右的锌钛合金镀层,并证实具有良好的抗蚀能力。为进一步提高合金
Preface The zinc-titanium alloy coating first appeared in Japan in the early 1960s and made continuous progress in more than two decades. Due to its excellent corrosion resistance, it has drawn extensive international attention. Now, zinc-titanium alloy electroplating solution has developed from non-aqueous solution to aqueous solution, from cyanide to cyanide-free; alloy coating also increased the content of titanium, so that the coating in harsh corrosive environment showed more significant corrosion performance. Some people from the domestic alkaline solution also deposited about 0.5% titanium zinc alloy coating, and confirmed with good corrosion resistance. To further improve the alloy
