Abstract:The article deals with the process of surface remelting of steel 41CrAlMo7 by electric arc (TIG) in the presence of powders with a defined chemical composition. Commercially available powders Pulnierpulver based on calcium cyanamide (CaCN2) (source of nitrogen) and Durborit G based on boron carbide B4C (source of boron) were remelted. The effect of remelting on the change of microstructure in the remelted area was examined to achieve an increase in hardness and resistance to abrasive wear. The measurements of … Show more
