Magnesium Alloy Introduction AZ31B Magnesium Alloy Bar anticorrosion properties improvement via a novel surface treatment method. In this regard, the praseodymium (Pr)-based film formation on the Mg-alloy surface at different film formation conditions (i.e., pH, time, temperature) were investigated. The composition of the generated Pr-based film on the Mg-AZ31 alloy surface was characterized in...
