On this examine, steel abrasion experiments have been carried out on an automated grinding system for chrome steel 304. Experiments ended up done at unique grinding situations for conditions of warmth-addressed samples and samples of their offer condition. The martensite stage transformation through grinding was analyzed by way of microstructure observation benefits and surface area hardness, microhardness measurements. The analysis outcomes display which the abrasion resistance of SUS304 metal enhances substantially when the sample is quenched in h2o Regardless that the floor hardness isn't going to boost. This phenomenon may be explained by the looks on the martensite phase via a period transformation mechanism due to plastic deformation of the fabric's surface area layer.
Observation results exhibit that soon after grinding, a substantial amount of martensite period appears over the surface area of warmth-taken care of samples. The macro surface hardness with the steel would not boost, but microhardness in different regions exhibits a transparent distinction, specifically in regions with significant concentrations of martensite.
