Enhancement of wear properties 316L stainless steel through shot blasting treatment and paste boronizing process / Muhamad Hafizuddin Mohamad Basir

Stainless steel is used widespread in various industries but it has poor wear resistance. This research was conducted to enhance wear resistance of 316L stainless steel by applying shot blasting and paste boronizing at ideal parameters. Three phases were involved in this study in which each of the phases contributes to each of the research objectives which consist of selection of ideal parameters for shot blasting, selection of ideal parameters for paste boronizing and wear resistance characterization. Data were collected and analyzed which concentrating on the samples' micro structure, X-ray Diffraction (XRD), microhardness, wear evaluation, surface roughness and density. Shot blasting improves the case depth of boride layers formed after performing paste boronizing by boosting the boron diffusion owing to the grain refinement created by shot blasting. Ideal shot blasting and paste boronizing parameters produce the greatest case depth of boride layers with highest surface hardness on 316L stainless steel which leads on improving its wear resistance.
