Determination of the conditions of boronizing steel with heating by laser radiation

Special features of boronizing iron and steel using a continuous-wave CO2 laser

“…Processes of laser alloying after which the heat treatment of the parts is unnecessary present a special interest. Laser boronizing is one such process.The use of pulse and continuous-wave low-power lasers for boronizing the surface of iron-carbon alloys can provide molten alloyed layers that contain boride phases 0.15-0.2 mm thick and up to 2 mm wide [1,2]. It has been shown in [3] that after boronizing iron and steels with the help of a continuous CO 2 laser with a power of up to 3 kW the thickness of the boronized layers increases to 0.4 mm and the width increases to 6 mm.…”
