研究了ＧＣｒ１５钢基体上火焰喷涂ＦｅＮｉＢＳｉ合金的超塑性及其变形，以及超塑变形时涂层与基材间的协调关系．涂层合金经超塑变形后，其内部孔洞消失，涂层与基材之间产生冶金结合．
The superplasticity and deformation of flame sprayed FeNiBSi alloy on GCr15 steel substrate were studied, and the coordination between coating and substrate during superplastic deformation was studied. After the coating alloy by superplastic deformation, the internal voids disappear, metallurgical bonding between the coating and the substrate.
