Abstract

An investigation was made of the physical properties of Sn and Sn-Zn alloy electroplates, Zn-treated HK-31 and AZ-31 Mg alloys. The Mg specimens were Zn-treated prior to the application of platings. Specimens were cleaned and electroplated with 0.0005 in. of Sn or Sn-Zn alloy by various procedures. Specimens were then visually examined for defective platings. Specimens which exhibited no defects were given adhesion, heat cycling, and salt spray exposure tests. None of the procedures produced a successful electroplate on the AZ-31 alloy. Attractive platings were obtained on the HK-31 alloy and these platings exhibited excellent adhesion and thermal shock properties but poor salt spray resistance.
