Abstract
This study investigates the effects of different electroless nickel-phosphorus (Ni-P) plating baths on the micro-arc oxidation (MAO) layer of AZ31 magnesium alloy. The research compares the corrosion resistance and adhesion properties of coatings using carbonate-based and sulfuric acid-based nickel formulations. The carbonate-based nickel formulation showed better corrosion resistance and adhesion, while the sulfuric acid-based formulation had uneven distribution and interface erosion. This study highlights the formation of NaMgF3 nanoparticles during the initial stages of nickel deposition, which affects the coating's density and adhesion. The findings provide valuable insights for enhancing the performance of MAO and electroless nickel deposition, with potential industrial applications in improving the durability and functionality of magnesium alloys.
