Description of the development:
()
Development of high-performance, energy-resursosohrannoy, ecologically-friendly technology diffusion and strengthen the instruments presform by nitriding in a glow discharge plasma. Due to the highly concentrated energy glow discharge in hydrogen-saturating the environment to ensure receipt of fortified high hardness of the surface layers with optimal properties for specific operating conditions that will ensure the durability of Visoko tools and equipment.     It is known that nitriding is one of the most effective methods to improve the wear resistance of machine parts and tools. However, traditional methods of gas nitriding are held in an environment of ammonia and have a greater duration of a cycle / hour to 72. /, Resulting in large losses of electricity and gas, and environmental pollution.      The use of highly concentrated energy sources, in particular the glow discharge and hydrogen-saturating the media, greatly intensifies the process of nitriding. In this case, several times the duration of the diffusion saturation decreases by an order of decreasing costs elekroenergii and gases are excluded hydrogen embrittlement of the metal and increases its flexibility it is possible to control the properties of the nitrided layer, expanding class of materials that lend themselves to nitration viyupochaetsg pollution sredy.Predyduschie industrial testing cutting tool fortified according to this technology have shown increased wear resistance of 2 to 5 times.      The novelty of the project: First developed technology tools to enhance the plasma glow discharge in hydrogen-saturating media optitimizatsiey properties of nitrided layers, depending on the operating conditions.      Vikonannya stages: 1. The theoretical justification for increasing the strength and znosostiykosi tools after application of the technology of nitriding in a glow discharge in hydrogen-free environments. 2. Development of methodology of experimental studies of technological modes of strengthening steel surfaces based on their chemical composition. 3. Pilot studies with the development of processing methods of strengthening. 4. Comparative industrial testing instruments and fortified presform. Development of optimal tools and technologies to strengthen presform and recommendations.
