The basic purpose of work is an improvement of manufacturing technique of integral cylindrical gears cluster by electro-erosion processing (EDM) of working surfaces of teeth the closed cylindrical gear of external gearing with application of chemicothermal processing for increase of their contact durability. The quality of the surface layer of teeth working surfaces of gears in a gas turbine engine using EDM has been investigated. The influence of modes EDM on the quality of working surfaces and their interconnection with roughness has been established. The surface chemical analysis made on proposed and serial technologies has been accomplished.
