英文摘要	The phase structure and interface diffusion of ferrum and aluminumin in the plasma welded high Al bronze coatings with three different temperatures of thermal diffusion were investigated by optical microscopy, X-ray diffractometry, scanning electron microscopy and energy dispersion spectroscopy. The interface bonding strength was measured by tensile test. The tribological properties were studied by pine-on-disk wear machine. The results show that the microstructure segregation of high Al bronze plasma welding coatings are improved by thermal diffusion process. Thermal diffusion widens the metallurgical layer, and significant element diffusion is observed, the bonding strength reaches 448.93 MPa after thermal diffusion at 650. The best tribological properties are obtained after thermal diffusion at 480, which caused by the species distribution of the hard and soft phases and the Fe content. The wear mechanisms are abrasive wear, which is the dominating wear mechanism, fatigue wear and adhesive wear. © 2016, Science Press. All right reserved.
