Abstract

Abstract: Nitriding test of 25Cr3MoA steel gear was carried out. The results show that when the depth of nitrided layer is 0.35-0.41 mm, the problem of the pulse-like and network-like nitride appearing in the microstructure of gears and internal splines during long-term nitriding can be solved by means of the three-stage nitriding process.

Key words: 25Cr3MoA steel, gear, internal spline, three stage nitriding, microstructure
