Stainless Steel Coatings

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.

Low Pressure Plasma

Nonequilibrium low-pressure plasma discharges are extensively studied for their applications in the field of decontamination and sterilization of medical devices. The aim of this contribution is to discuss and demonstrate feasibility of oxygen low-pressure inductively coupled plasma (ICP) discharges for removal of various kinds of biological contamination. We demonstrate the ability of ICP discharges for the sterilization of bacterial spores and the removal of biological contamination from proteins and pyrogens.

Low Pressure Plasma Spraying

A sprayed MoB/CoCr cermet coating was formed on 310S stainless steel by low pressure plasma spraying (LPPS), and its durability in the molten Al-12.07wt.%Si has been investigated by SEM、EDS and XRD. The immersion test revealed that the MoB/CoCr coating has much higher durability without dissolution in the molten Al-12.07wt.%Si alloy. Little change of crystal structure, mainly composed of ternary borides of Co2MoB2 and CoMoB, suggesting that the ternary borides have much higher durability.
