摘要：

The process of electroless Ni-P-polytetrafluoroethylene (EN-PTFE) plating was investigated in this study. The microstructural analysis was conducted with scanning electron microscopy. Differential scanning calorimetry was used to study,the phase transition of the coating during heat treatment. The mechanical and tribological properties were measured using a hardness tester. and a ring-on-disk machine. The corrosion resistance of the coatings was. evaluated by polarization measurements. It was found that the microhardness and corrosion resistance of EN-PTFE decreased with increasing PTFE content. PTFE had little effect on the phase transition of the coating and a low surface energy. The results of wear test show EN-PTFE composite coatings had a low coefficient of friction of 0.1 and good anti-wear properties.
