Abstract
Aluminum bronze powder was deposited onto Q345R using positive and reverse polarity plasma arc surfacing. Through the analysis of formability and welding defect, it shows that the formability and welding defect of reverse polarity plasma arc aluminum bronze surfacing layer are better than the positive polarity. Aluminum bronze powder plasma surfacing layer was obtained by using reverse polarity under different currents, and the optimal surfacing current was obtained by changing the hardness and wear resistance of the surfacing layer. The results show that the current for the highest hardness of the aluminum bronze surfacing layer is 120A, and the current for the best wear resistance is 110A.
