Within this examine, steel abrasion experiments have been executed on an computerized grinding machine for chrome steel 304. Experiments were performed at various grinding instances for circumstances of heat-taken care of samples and samples within their provide state. The martensite phase 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 increases noticeably in the event the sample is quenched in drinking water While the surface area hardness will not improve. This phenomenon may be explained by the looks on 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, a significant amount of martensite period appears over the floor of heat-addressed samples. The macro surface area hardness of the metal doesn't increase, but microhardness in several locations reveals a clear difference, particularly in regions with substantial concentrations of martensite.
Keywords and phrases: Section transformation, heat procedure, abrasion resistance, stainless-steel 304, abrasion experiments.
