Abstract
In the roughened surface of 25# steel composite with a plastic layer which consists of PPS、TLCP、TPI and Graphite. The dry friction performance of composite material was tested in room temperature environment. The surface of wear was observed and analyzed by scanning electron microscope. Finally, to analyze the bond strength between the metal material and plastic work layer through the bond strength test. The results showed: the composite material has excellent tribological properties, after the shot peening coarsening in the metal matrix surface can well improve the binding force between plastic layer and metal matrix, the thickness of plastic layer has a certain effect to bond strength, the maximum bond strength was obtained when the thickness of 1.5 mm.
