Effect of Stages of Vacuum Carburizing on Deformations in Splines of Steels 16MnCr5, AMS6265 and 17CrNiMo7-6

Deformations of straight-sided splines (changes in the width of the hubs) of steels 16MnCr5, AMS6265 and 17CrNiMo7-6 are studied after different treatments, i.e., a hold at 1050°C without carburizing and with slow cooling to room temperature, vacuum carburizing with subsequent slow cooling to room temperature, and vacuum carburizing with subsequent oil quenching. The sizes of the deformations are shown to depend on the grade of the steel. The lowest deformations are obtained for steel 16MnCr5.
