It forces consistently to utillize to 14 electro-erosive passage-ways, gradually diminishing the height of mikrounevens and thermal affected zone. Possibility of realization in a current conducting, liquid environment, both electrochemical and electro-erosive, mechanism of destruction of material generated the idea of spatio-temporal combination of these processes within the framework of the single combined method of treatment. Systematic researches of the combined electroerosion - electrolyte - plasma method of treatment (EEEPMO), allowed to develop bases of theory and technology of the new combined method of treatment, find out the area of his effective industrial use. Electrochemical processes can influence on the terms of flowing of digit and subsequent destruction of material thus: 1.Electrode gas is a selection, forming gas-liquid layers, facilitates of electrolyte bridges and formation of plazma phase. 2.A key-in through MEP of current of electrolysis results in appearance volume and superficial sources heats which initiate the processes of the bubble and pellicle boiling of liquid phase. 3.Superficial new formations bring in the payment in balance of tension on MEP. Influence of electric digits on flowing of electrode processes and processes of transference shows up mainly in the following: -a hydrodynamic effect, concomitant a digit in liquids, is instrumental in the depassivation of anodal surface in the case of diffusive control of speed of anodal dissolution, facilitates taking of products of reactions in the volume of solution and evacuation them from a working area; -the thermal effect of digit is instrumental in a depassivation in the case of diffusive control of speed of dissolution, causes the increase of local conductivity of solution, influences on speed of homogeneous and getero chemical reactions, thatcan result not only in growth of current of electrolysis but also to the redistribution of speeds of electrode reactions with the proper change output on the current of basic reaction and degree of oxidization of ions of metal, transitory in solution. For the leadthrough of experiments setting was developed. It is created on the base of electro-erosive machine-tool of SELD-04, which was additionally equipped the source of feed for electrochemical treatment and station of preparation of electrolyte. Forming of surface is investigational at electro-erosive and electrolyte-plasma treatments. Conformities to the law of forming of surface are certain at an electromachining. The physical phenomena which take a place on-the-spot detail at passing of electric current from a single impulse are analysed. Dependence of roughness of surface is set at an electromachining from the parameters of generator of technological current. The process of electrolyte-plasma a form is education of wire electrodes is considered. The parameters of pulser, which realization of process, composition of electrolyte and his concentration, is possible at are set Product Description popup.authors popup.nrat_date 2020-04-02 Close
