Furnace superalloy applies in harsh environment within the erosion of high temperature and oxidizing atmosphere. With plasma powder surfacing technology, iron-based alloy powder was sprayed on the surface of 310S stainless steel to form oxidation layer that increase the oxidation resistance and reduce the cost of materials. With optimum technological parameters, this paper carried out oxidation test of 100 hours on iron-based cladding alloy and furnace alloy at 1200℃. The technique of XRF, XRD and EDS were used to characterize composition, oxide morphologies and surface mechanical properties. The results showed that：Element composition of cladding layer formed by Plasma powder surfacing was well distributed. Its oxidation weight gain rate of 100 hours was 0.4552g/m2h, belonged antioxidant level. The oxidation weight gain rate of furnace alloy was 1.4617g/m2h, belonged time-antioxidant level. And on the mechanical comparison test, surfacing alloy was relatively excellent than furnace alloy.
