Technologies of molecular reinforcement of friction surfaces of gearing gears and bearings of the starter motor of gas turbine aircraft engines NK-14ST

The results of the development, research and approbation of effectiveness of technology of hardening of machine parts and devices by method of diffusion molecular reinforcement of friction surface defects are presented. The technology is implemented in production conditions of PJSC «Kuznetsov» and provides a significant increase in service life due to slowing the development of fatigue damage to the teeth of conical gears and rolling bearings of the starter motor NK-14ST.
