## Abstract A stannate chemical conversion process followed by an activation procedure was employed as the preβtreatment process for AZ91D magnesium alloy substrate. Zn was electroplated onto the preβtreated AZ91D magnesium alloy surface from pyrophosphate bath to improve the corrosion resistance a
A permanganate-rare earth metal salt (REMS) chemical conversion bath was applied to a sample of AZ91 magnesium alloy in this study, a red-brown conversion coating formed subsequently on the sample surface. The test results of this coating with a scanning electron microscope (SEM) showed that there e
