Plasma transferred arc forming technology for remanufacture
The plasma transferred arc (PTA) forming remanufacturing technology was introduced in this paper. This technology includes plasma surfacing, deposition and rapid forming technology. With self-developed plasma forming system, the thrust of engine cylinder body was remanufactured by PTA powder surfacing. In the concrete, the Ni15 alloy was deposited on the thrust face of the body in order to recover its dimension. In addition, the remanufacturing forming with Fe-based, Inconel 625 alloy was studied. The microstructure and hardness of the as-deposited materials were investigated.
