Determination of the limiting values of the laser parameters to heat treatment of powder carbon steels surface

“…An analysis of the literature shows that most studies of laser exposure cover its effect on cast steels [8][9][10][11][12][13], and laser processing of powder products is usually performed to reduce surface porosity, to obtain coatings to restore parts [14][15] or deposit metal powders [16][17]. Since the structure and physical properties of powder alloys differ from cast alloys (primarily, due to the presence of pores), it is necessary to establish optimal processing conditions for hardening the surface of powder steels with a laser, the main of which are the density of laser radiation power and the speed of spot movement laser [18][19].…”
