On this review, metal abrasion experiments were performed on an automated grinding product for chrome steel 304. Experiments were performed at distinct grinding moments for scenarios of warmth-dealt with samples and samples of their source point out. The martensite section transformation throughout grinding was researched by way of microstructure observation effects and floor hardness, microhardness measurements. The exploration effects exhibit the abrasion resistance of SUS304 steel improves considerably when the sample is quenched in h2o even though the area hardness won't enhance. This phenomenon might be described by the appearance of your martensite period by way of a phase transformation system as a consequence of plastic deformation of the fabric's surface area layer.
Observation final results display that right after grinding, a significant amount of martensite period appears on the area of heat-treated samples. The macro floor hardness in the metal won't enhance, but microhardness in different parts displays a transparent change, particularly in locations with significant concentrations of martensite.
