Abstract Influences of anion surfactant (sodium dodecyl benzene sulfonate, sodium lauryl sulfate) and cationic surfactant(triethanolamine) on deposition of nickel-phosphorus-nanometer Al2O3 composite coatings were investigated. Influences of sorts and addition quantity of surfactant on deposition rate,hardness and abrasion resistance of coatings were discussed. The appearances of the various composite coatings were observed by scanning electron microscope (SEM).The content of nanometer Al2O3 particle was measured by energy dispersion spectroscopy (EDS). The experiment results show that the better amounts of two anion surfactants are both 50 mg/L and cationic surfactant is 100 mg/L in nanometer composite plating bath. The cationic surfactants deposit has high content of nanometer Al2O3，fast deposition velocity，good abrasion resistance and uniform dispersion of nanometer Al2O3 particles among three surfactants. The nano-Al2O3 composite deposit has higher microhardness and better abrasion resistance than that of electroless Ni-P and micro-Al2O3 composite electroless Ni-P.
