In this paper, electro-less Ni-P-ZrO2 composite plating was preformed on Zr-8Al alloy. The microstructure, microhardness, wear resistance and corrosion resistance in 3.5 wt% NaCl solution of electro-less composite platings for different ZrO2 addition were investigated. The results show that the microhardness of electro-less Ni-P-ZrO₂ composite plating was improved compared with that of electro-less Ni-P plating. The microhardness and wear resistance of electroless Ni-P-ZrO2 composite plating for 4g/L ZrO2 addition is super. The corrosion resistance of the electroless Ni-P-ZrO2 composite plating is a bit lower than that of electro-less Ni-P plating, yet the composite plating after corrosion is still complete. So the corrosion resistance of the electroless Ni-P-ZrO2 composite plating for 4g/L ZrO2 addition is still better. The Ni-P-ZrO2 plating on Zr-8Al alloy is potential to applied for moving parts in space which require excellent wear resistance and good corrosion resistance.
