Implantation of differential parts with tungsten Carbide-based materials

The purpose of this work was to solve the problem of increasing the wear resistance of car transmission differential parts by implanting them with subsequent treatment by surface plastic deformation.
Methods. To achieve the goal set in the work, the following methods of processing the studied parts were used: correcting the geometry of the spike of a crosspiece that was in use by turning on a rotary-screw machine; applying graphite-tungsten coating to surfaces prepared for implantation and drying it; directly implanting on an installation specially designed for this process; hardening the implanted surface by running in with a two-roller head; fine grinding of the hardened surface of the crosspiece spike; investigation of the wear resistance of hardened surfaces according to the standard methodology; evaluation of the resource of restored and hardened parts.
Results. Based on the conducted studies aimed at increasing the wear resistance of the differential transmission parts of the car, it was found that the properties of the restored and hardened surfaces of the differential crosspiece depend on the composition and structure of the formed surface layer by implanting tungsten-containing materials and subsequent running-in with a two-roller head. In particular, it was found that the wear resistance of the working surfaces of parts repaired and hardened using the new combined technology increases by 2.07 times compared with the new ones with a comparable increase in service life.
Conclusion. Thus, the goal has been achieved, namely, the problem of increasing the wear resistance of the differential transmission parts of the car by implanting them with subsequent treatment by surface plastic deformation has been solved. The results obtained in this work can find practical application in the organization of resource-saving and importsubstituting technologies, which in turn will contribute to the creation of high-tech industries.
