The Effect of Al₂O₃ Concentration on Properties of Ni-W-P-Al₂O₃ Electroless Composite Coating

Abstract:

Ni-W-P-Al2O3 electroless composite coating was successfully co-deposited on 45 steel substrate using electroless plating. Optical microscope (OM), micro-hardness tester and potentiodynamic polarization were used to analyze the morphology, micro-hardness and corrosion resistance of the composite coating. The effect of Al2O3 concentration in the plating solution on the micro-hardness and corrosion resistance of the composite coating was mainly discussed. The results show that Al2O3 particles co-deposit with Ni-W-P homogeneously. The micro-hardness and corrosion resistance of the coating are improved with the increasing of Al2O3 concentration in the plating bath, and then decrease at a high Al2O3 concentration.
