Microstructure of 316L Stainless Steel Coating Deposited by the Low Pressure Plasma Spray

Article Preview

Abstract:

Original equiaxed 316L stainless steel coatings were successfully deposited by the low pressure plasma spray. For comparison, the coatings of 316L stainless steel with normal lamellar structure were also prepared by the air plasma spray (APS). The microstructures were investigated using optical micrograph (OM). The results show that the microstructures of LPPS 316L stainless steel coatings reveal the fine equiaxed microstructures like the solidified stainless steels,which are significantly different from that of APS coatings with lamellar structures.
