During this study, steel abrasion experiments had been performed on an automated grinding system for stainless-steel 304. Experiments ended up executed at distinctive grinding times for instances of heat-handled samples and samples within their provide state. The martensite phase transformation in the course of grinding was researched by way of microstructure observation benefits and floor hardness, microhardness measurements. The investigation benefits present that the abrasion resistance of SUS304 steel increases noticeably in the event the sample is quenched in drinking water Though the surface area hardness doesn't increase. This phenomenon is usually spelled out by the appearance from the martensite section by way of a phase transformation system as a consequence of plastic deformation of the material's surface layer.
Observation success demonstrate that right after grinding, a significant degree of martensite period appears to the surface area of warmth-handled samples. The macro area hardness on the steel won't boost, but microhardness in various regions shows a transparent distinction, specifically in regions with significant concentrations of martensite.
Keywords and phrases: Section transformation, heat cure, abrasion resistance, stainless steel 304, abrasion experiments.
