Effect of Shot Blasting on Paste Boronizing of 316L Stainless Steel

Abstract

This investigation was conducted to study on the effect of shot blasting on the case depth of boride layers produced and microhardness after performing paste boronizing on 316L stainless steel. 250 micron diameter of glass beads had been used in the process of shot blasting with variation in the blasting pressure. Paste boronizing was performed at 850°C with 8 hours of soaking time. The samples involved were tested and analyzed on the microstructure and microhardness. Boride layers of FeB and Fe2B formed due to paste boronizing improve the microhardness of 316L stainless steel and the effect of shot blasting with increasing the blasting pressure increase both of case depth of boride layers and microhardness on the studied metal.

The Effect of Sandblasting on Properties and Structures of the DC03/1.0347, DC04/1.0338, DC05/1.0312, and DD14/1.0389 Steels for Deep Drawing

“…The formation of ultrafine or nanocrystalline microstructure in the surface layers of the materials often leads to considerable improvements in their tribological and mechanical properties [18,19]. Strain-induced grain refinement resulting from sandblasting has been reported in many studies [20][21][22]. The effect of sandblasting on surface properties of C45 steel sheet for adhesion was investigated in [23].…”
