In order to improve the corrosion and wear resistance of the coatings of electroless plating Ni-Cu-P and broaden its application, an optimizing mathematical theory test has been applied in this research. The processing parameters have been optimized and some Ni-Cu-P coatings have been obtained with smooth and glittering appearance. At the same time, the composite complexants can prevent copper from depositing first and obtain coatings with strong adhesion. The porosity of Ni-Cu-P coating (20 μ m) ranked class 9. The coating color changes after at least 800 second when HNO3 dropping on. XRD diagram shows that the coating structure is amorphous when the amount of CuSO4 • 5H2O in the bath is less than 0.5g/L. The surface appearance of deposition is typical crystalline cells by SEM, which rank close and neatly.
