Abstract

For study the surface quality of film of n-Al2O3/Ni-P electroless composite plating,by orthogonal test,the process conditions of n-Al2O3/Ni-P composite electroless were optimized as follows: temperature of 86 ℃,pH value of 5.2,60L/h of agitation quantity,8g/L of nano-Al2O3 content,2g/L of A and 40mL of B of effects surfactants.Using the hardness,porosity,surface-roughness-degree as evaluation criterion,results show that the surface quality of film of n-Al2O3/Ni-P electroless composite plating is better than that of film of Ni-P electroless plating: the surface of film of n-Al2O3/Ni-P composite electroless is even and dense,porosity is 9 grade,hardness can reach 620HV,and surface roughness degree is 0.628μm.
