Abstract: A series of dry friction tests of metal/ceramic composite coatings and carbon steel coating against mild carbon
steel were carried out under room temperature using an SRV Friction and Wear Tester. The tribological behaviors of plasma sprayed CoCrMoSi+Al2O3ZrO2,
CoCrMoSi+Fe3O4 and Cr1Mn1C1 carbon steel coatings were compared by means of SEM and Scanning Electron Acoustic Microscopy (SEAM). The
results show that microcutting, the propagation and coalescence of micro-cracks of the materials appear in the wear process, adhesion
wear still is the main mechnism of the metal/ceramic composite coatings.

Key words: plasma spraying, composite coating, wear mechanism
