Improving the Durability of Machine Parts Using a Combined Method

Abstract:

A combined processing method for improving the performance features of machine parts (durability), that works under intense wear and high lubricated or boundary friction has been developed; a working installation based on a CNC lathe has been developed. The research on resulting surface hardness material of steels: С45Е; 1.1191 (1 option); SA-240 TP 310S (2 option); 34CrNiMo6, 36CrNiMo4, 40NiCrMo4KD (3 option) and hardening depth variation under different combined processing conditions has been carried out. Surface roughness parameters have been calculated. The suggested method can increase the operational life of a machine part due to improving features, such as surface hardening, creating a favorable surface topography.
