| Abstract: |
| Objective To investigate the influence rules of FC4 surfactant and PTFE addition amount on the quality of the coating, the volume fraction of PTFE in the coating and the friction-wear properties. Methods Different electroless Ni-P-PTFE composite platings were obtained by changing the addition amount of FC4 and PTFE. The morphology of the coatings was observed by Scanning Electron Microscope and the volume fractions of PTFE in the coatings were measured and calculated by combining Energy Disperse Spectroscopy with histogram method. The changing rules of the quality of the coatings and the volume fraction of PTFE in the coatings with the addition amount of FC4 and PTFE were investigated,and the tribological property of the coatings was analyzed. Results The best coating with the biggest volume fraction of PTFE was obtained when the addition amount of FC4 was 0. 3 g/ L in the electroless Ni-P-PTFE composite plating process, and the coating with the lowest wear rate was prepared when the volume fraction of PTFE in the coating was 10% . Conclusion The volume fraction of PTFE in the coating increased with increasing addition amount of PTFE in the plating solution, and there was a minimum wear rate when the volume fraction of PTFE in the coating changed within the limit. |
