Abstract
Polytetrafluoroethylene (PTFE) is known as a solid material with high lubricating property and low friction coefficient. The application of PTFE is significant to improve the tribological properties of coating. In this paper, Scanning electron microscopy (SEM), Energy Dispersive Spectrometer (EDS), X-ray diffractometry (XRD), Microhardness test and friction and wear experiment are adopted to study the effects of PTFE content on the structure, morphology and properties of coating. The results show that the addition of PTFE particles can reduce spherical particle size and increase the hardness and friction properties of coating when typical cauliflower shaped druse and excellent interface binding characteristics are maintained. If the content of PTFE is too much, some area of coating is prone to powder hoarding which may lead to the decrease of coating density, hardness, and friction coefficient stability.
