| Abstract: |
| Several Fe-based alloy powders were designed by using orthogonal design method, water fuel plasma arc equipment was adopted to hardfacing Q345 steel . The effects of Cr, Mo, Si, C additions on hardness, microstructure and wear properties of the hardfacing metal were investigated. The results show that the microstructure of the hardfacing metal is composed of a large amount of M7C3 carbides and eutectic structure. The highest hardness of the hardfacing metal is HRC56 . 8 , which has good wear property. The experiments indicate that it is feasible to investigate on the power surfacing by using water fuel plasma arc equipment . |
