During this study, steel abrasion experiments had been performed on an automated grinding system for stainless-steel 304. Experiments ended up done at distinctive grinding times for instances of heat-treated samples and samples in their supply point out. The martensite section transformation throughout grinding was studied via microstructure observation outcomes and surface hardness, microhardness measurements. The study outcomes show which the abrasion resistance of SUS304 metal enhances drastically once the sample is quenched in water even though the area hardness would not raise. This phenomenon might be discussed by the appearance of the martensite period by way of a phase transformation system resulting from plastic deformation of the material's surface layer.
Observation success exhibit that right after grinding, a substantial amount of martensite period appears over the floor of heat-dealt with samples. The macro surface area hardness of the metal doesn't raise, but microhardness in numerous areas demonstrates a clear variance, especially in locations with large concentrations of martensite.
Keywords: Stage transformation, warmth remedy, abrasion resistance, chrome steel 304, abrasion experiments.
