On this examine, metal abrasion experiments ended up executed on an computerized grinding device for stainless steel 304. Experiments were performed at various grinding instances for situations of heat-taken care of samples and samples inside their provide condition. The martensite stage transformation for the duration of grinding was analyzed by way of microstructure observation effects 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 h2o While the floor hardness will not boost. This phenomenon may be explained by the looks with the martensite stage through a section transformation mechanism as a result of plastic deformation of the material's area layer.

Observation benefits present that following grinding, an important number of martensite stage seems about the surface area of warmth-taken care of samples. The macro surface hardness with the steel would not enhance, but microhardness in different spots displays a transparent variation, especially in areas with higher concentrations of martensite.
Key terms: Stage transformation, warmth remedy, abrasion resistance, chrome steel 304, abrasion experiments.
