Formation of Hardened Surface Layer during Laser Cutting of Gears of Tooth Gears Made of Structural Alloy Steel Grade 40Kh
Abstract—The structural features and microhardness in the zone adjacent to the edges of the cut during laser cutting of gear blanks from a sheet of 40Kh steel 6 mm thick were studied. The possibility of combining laser cutting with surface hardening is shown. On average, the hardened surface layer in different sections of the cut has a thickness on the order of 150–250 μm with a maximum hardness approximately equivalent to 46–58 HRC, which is quite comparable to the hardening of 40Kh steel with most surface treatments.
