Abstract

The possibility of using ultrasonic surface hardening with implementing the indenter tangential oscillations to the deformed surface to improve the quality of the detail surface layer produced from low carbon steel and ferrous alloys is considered in the paper. The mathematical description of the trajectory of the relative displacement of the instrument and the detail is presented. It is established that the important technological parameter influencing the character of the formed micro-geometry is the angle between the instrument vectors and the detail speed. The effect of the technological factors of the ultrasonic surface hardening on the amplitude and spacing parameters of the surface roughness are revealed. The results of the research showed that the ultrasonic processing at the tangential oscillations of the indenter allows forming a stable micro-geometrical state of the surface layer with low values of the amplitude and spacing parameters on the details made from non-ferrous alloys and low carbon steels.
