Electroless Ni–P–B coatings on magnesium alloy AZ91D: influence of nano Al2O3 on corrosion, wear, and hardness behaviour

“…Because of the inclusion of phosphorus and boron in coated samples, the current density (1.11×10 -6 A cm −2 ) decreased and the corrosion potential (-0.365 V) increased after electroless plating of Ni-P-B coating at 0 wt% [53][54][55]59]. The decrease in current density is due to the high thickness and uniform Ni-P-B coating on AZ91D magnesium alloy, which prevents NaCl solution from penetrating the substrate without any defects or micropores [59,60]. When Al 2 O 3 reaches 1% weight, the current density decreases (from 1.1×10 -6 to 5.01×10 -7 A cm −2 ), and the corrosion potential increases (0.007 V).…”
