The technology of deep ion-plasma nitriding has been developed in this article and its practical implementation for disc saws made of U8G steel has been carried out. The technology of deep ion-plasma nitriding was implemented on the STANKIN-APP-1 installation. A circular saw made of U8G steel and witness samples of the same steel were selected as the object of research for subsequent measurement of microhardness and phase analysis. In order to avoid deformation of the saw blade, a tooling was developed, since the thickness of the saw blade is 0.95 mm. The results of resistance tests have shown the feasibility of using this technology for disc saws. The total resistance of the teeth of disc circular saw made of U8G steel increased by 4 times compared to a circular saw without nitriding.
