To meet the requirements of integrative mechanical properties and shielding effectiveness of nuclear radiations shielding materials, the boron-rich shielding coating (Fe67.5Ni23.5B9, in wt. %) were produced onto 321 stainless steel substrate (SS) by the air-plasma spraying technology. This type of coating-SS laminated composite will be likely to be used as protection against neutrons and γ rays from radiation shielding systems. The microstructure was characterized by scanning electron microscope (SEM), energy-dispersive spectrometry (EDS) and X-rays diffraction (XRD). The mechanical properties of Fe67.5Ni23.5B9 coatings were investigated, including adhesion strength, tensile properties and residual stress. The shielding effectiveness of the coating-SS laminated composite, including the slowing down of fast-speed neutrons, absorption for 0.4ev below thermal neutrons and the attenuation against 60Co and 137Cs γ rays were investigated. The results show that the produced Fe67.5Ni23.5B9 coatings-SS laminated composite possess homogeneous microstructure, satisfactory integrative mechanical properties and shielding effectiveness which testify the possible application in radiation shielding systems.

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.
