Within this examine, steel abrasion experiments ended up executed on an computerized grinding machine for stainless steel 304. Experiments were performed at distinct grinding instances for situations of warmth-dealt with samples and samples inside their offer condition. The martensite stage transformation through grinding was examined by microstructure observation success and area hardness, microhardness measurements. The exploration effects exhibit the abrasion resistance of SUS304 steel improves considerably when the sample is quenched in h2o While the floor hardness isn't going to boost. This phenomenon may be defined 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 to 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.
