With this analyze, metal abrasion experiments were conducted on an automatic grinding unit for stainless-steel 304. Experiments were performed at various grinding instances for situations of heat-taken care of samples and samples within their provide condition. The martensite stage transformation for the duration of grinding was analyzed by way of microstructure observation benefits and floor hardness, microhardness measurements. The investigation benefits demonstrate the abrasion resistance of SUS304 steel improves noticeably in the event the sample is quenched in drinking water While the floor hardness isn't going to boost. This phenomenon could be described by the appearance of the martensite section by way of a stage transformation mechanism due to plastic deformation of the fabric's floor layer.
Observation final results display that following grinding, an important number of martensite stage appears over the floor of heat-addressed samples. The macro floor hardness from the metal isn't going to improve, but microhardness in various regions shows a transparent big difference, specifically in areas with higher concentrations of martensite.
Key terms: Stage transformation, warmth remedy, abrasion resistance, chrome steel 304, abrasion experiments.
