ce morphology of the Ni-P-PTFE composite coating was observed and its tribological properties were tested．The results showed that the optimal deposition rate was obtained with 25 g／L nickel sulfate，30 g／L sodium hypophosphite， and l o mL／L PTFE at temperature(92 4-2)℃ and pH 4．6． The composite coating has a friction factor ranging from0．1 6 t0 0．26．showing good wear resistance．
