| Abstract: | The self-lubricative composite coatings were prepared by electrodeposition.The process parameters and the determining step of electrodepositing process were studied.The optimal process parameters were:CuSO_4 85 g/L,H_2SO_4 55g/L,PTFE 40 g/L,current density 4.0 A/dm~2,reaction temperature 25℃,reaction time 60 min.The composite films show excellent tribological properties,acting as self-lubricating coatings with low friction coefficients and high hardness.And the effect of particles concentration on the determining step was also discussed. |
