Fabrication and Corrosion Resistance of a Superhydrophobic Ni-P/Ni₃(NO₃)₂(OH)₄ Multilayer Protective Coating on Magnesium Alloy.

ABSTRACT: A superhydrophobic multilayer coating with excellent corrosion resistance has been fabricated on an AZ61 magnesium alloy through electroless plating and hydrothermal treatment. The surface morphologies, chemical characteristics, wettabilities, and corrosion resistance of the multilayer coating were characterized and discussed. The results show that the electroless Ni-P coating on the magnesium alloy exhibits a nodular structure with micropores and lower corrosion resistance. However, a dense Ni₃(NO₃)₂(OH)₄ layer, a porous Ni₃(NO₃)₂(OH)₄ nanostructure layer, and a stearic absorbing layer are grown on the surface of the Ni-P coating with superhydrophobic characters and higher corrosion resistance after hy
