Abstract

Abstract: The aims of this work are to prepare a novel epoxy resin‐polytetrafluoroethylene (expressed as EP/PTFE) bonded solid lubricating coating filled with flake aluminum. The focus is to study the effects of two different flake aluminum (floating type and non‐floating type) on the tribological performance and anti‐corrosion capability of the coating. A CSM friction tester was applied to evaluate the tribological performance of the coating. The electrochemical technique was applied to study the corrosion resistance of the coating. And the experimental results showed that both types of flake aluminum can ameliorate the tribological performance and anti‐corrosion properties of the EP/PTFE lubricating coating. Moreover, compared with floating flake aluminum, the incorporation of non‐floating flake aluminum significantly improved the tribological properties and corrosion resistance of the EP/PTFE coating due to its good dispersibility, greater enhancement effect on mechanical performance and stronger barrier properties. Abstract : We develop a flake aluminum reinforced epoxy resin‐polytetrafluoroethylene bonded solid lubricating coating with both excellent tribological properties and corrosion resistance.
