Abstract

The subject of research in the master's qualification work is the mechanisms for modifying the structure of the surface layers of steel parts using the doping components and the energy of the arc of the graphite electrode. The work consists of six main parts: 1. Modification of surfaces of steel parts with application of arc of coal electrode; 2. Research, modification of surfaces of steel parts using a plasma of a coal electrode; 3. Development and substantiation of parameters of technological process of restoration of pinion gear; 4. Designing equipment with numerical control for surface modernization; 5. Calculation of economic efficiency of innovation decision; 6. Occupational safety and security in emergencies. The object of the study is the processes that accompany the formation of the structure of the surface layers under the influence of the arc energy of the graphite electrode and doping impurities. The main goal of the qualification work is to develop an effective technology for the restoration of the working surfaces of the toothed gears of the gear shaft by using the alloying elements and the arc energy of the graphite electrode. In the work the technological process of restoration of a part of a gear-type shaft by the influence of plasma arc of a graphite electrode and doping impurities is developed.
