Abstract

Boronized stainless steel often contained insufficient thickness layer because the existences of high alloying element hinder the diffusion process that resulted into low hardness and wear properties. Thus, in this study, improvement of dispersion layer was performed by inducing surface deformation onto the surface of the material. The main objectives of this study is to investigate the effect single and double sand blasting on the abrasion and erosion wear properties of 304 stainless steel. Pin on disk tester was used in order to obtain the value of coefficient of friction that indicated the wear resistances and slurry erosion test rig was used to obtain the erosion wear properties. Surface deformation was conducted through single and double shot blasting process before boronizing was performed. The results indicated that by performing double shot blasting process, enhancement of dispersion layer was achieved, thus lead to enhancement of both abrasion and erosion wear behavior.
