摘　　要：PA and PA/MoS2 composite coatings were prepared by flame-spraying. The thermal properties, crystallinity, microstructure and tribological properties were investigated with Fourier transform infrared (FTIR), differential scanning calorimetry (DSC), scanning electron microscopy(SEM), and MM-200 model wear tester. Temperature influences the final morphological structure of the coatings. Tribological experiment results indicate that the MoS2 filled PA coating has different wear resistance compared with the PA coating without MoS2 filler. A high content of MoS2 decreases the hardness of composite coating and enhances the wear rate. The 1 %-3% content of MoS2 has advantages to the tribological ProPerties of PA composite coatings.
