Electroplating zinc transition layer for electroless nickel plating on AM60 magnesium alloys WANG Xiao-min(王晓民)1, ZHOU Wan-qiu (周婉秋)1,2, HAN En-Hou(韩恩厚)2 1. College of Chemistry and Life Science...: Electroplating zinc coating as transition layer of electroless nickel plating on AM60 magnesium alloys was investigated. The zinc film can be deposited in a pyrophosphate bath at 50-60 ℃ under......
also analyzed. LUAN et al[32] claimed that the copper deposit was well applied on magnesium alloy from acid and alkali copper electrolyte followed by electroless nickel plating. The relationship... Pre-electroless nickel plating It is difficult to obtain the adherent deposit on magnesium alloys with high content of aluminum such as AZ91D Mg alloy. However, the process that following pre......
