25 batches of 50Cr15MoV kitchen knives were analyzed by chemical composition analysis, surface roughness testing, corrosion resistance testing, metallographic examination, scanning electron microscopy. The results show that:(1) there is no linear relationship between the heavy metal migration of 50Cr15MoV kitchen knives and its corresponding element content, and there is no correlation between the heavy metal migration and the surface roughness; (2) The heavy metal migration of kitchen knives is significantly correlated with corrosion resistance, and the heavy metal migration is positively correlated with the corrosion points in statistics; (3) The heavy metal migration of the kitchen knives with the same material of 50Cr15MoV varies greatly, which is closely related to the microstructure of the kitchen knives. The morphology and distribution of carbide microstructure and the heat treatment process of products have great influence on the heavy metal migration of kitchen knives.
