On this examine, metal abrasion experiments ended up done on an computerized grinding device for chrome steel 304. Experiments were performed at various grinding instances for circumstances of heat-taken care of samples and samples within their provide state. The martensite phase transformation for the duration of grinding was analyzed by way of microstructure observation benefits and floor hardness, microhardness measurements. The investigation final results present that the abrasion resistance of SUS304 steel increases noticeably if the sample is quenched in drinking water Despite the fact that the surface area hardness doesn't increase. This phenomenon is usually stated by the looks in the martensite phase via a stage transformation mechanism due to plastic deformation of the fabric's surface area layer.
Observation outcomes show that just after grinding, a big level of martensite phase seems around the area of heat-treated samples. The macro floor hardness in the metal isn't going to improve, but microhardness in various places shows a transparent distinction, specifically in regions with significant concentrations of martensite.
Keywords and phrases: Section transformation, heat procedure, abrasion resistance, stainless-steel 304, abrasion experiments.
