On this review, metal abrasion experiments ended up done on an computerized grinding device for stainless steel 304. Experiments had been carried out at diverse grinding moments for scenarios of warmth-dealt with samples and samples inside their offer condition. The martensite period transformation through grinding was examined by microstructure observation effects and floor hardness, microhardness measurements. The exploration effects exhibit the abrasion resistance of SUS304 steel improves significantly in the event the sample is quenched in h2o While the surface area hardness will not improve. This phenomenon can be explained by the looks on the martensite stage via a period transformation mechanism because of plastic deformation of the fabric's floor layer.
Observation final results display that after grinding, a big volume of martensite phase seems within the surface of warmth-handled samples. The macro area hardness on the steel won't boost, but microhardness in various regions exhibits a transparent distinction, specifically in regions with superior concentrations of martensite.
Keywords: Period transformation, warmth treatment method, abrasion resistance, stainless steel 304, abrasion experiments.
