Abstract The article is devoted to the possibility of applying the methods of successive approximations in the analysis of the instantaneous scheme of the electric-traction netware. The described approach makes it possible to improve the accuracy of modeling the dynamic modes of traction power supply sections operation, and also makes it possible to significantly improve the process of modeling diagnostic and control systems for electric rolling stock at the design stage, based on a more accurate model of dynamically changing input parameters of the electric-traction netware, depending on their required level.

The paper provides information about the experience of using network schedules in the conditions of service locomotive depots that contribute to the observance of logical discipline in planning, drawing up calendar plans and managing repair work to restore traction engines of 2ES6 series of freight electric locomotives, as well as a set of measures to optimize the technological process of traction engines repair in the volume of TR-600. The analysis of the existing technological process of repair of traction engines allowed to reveal features of distribution of time of each operation in branches of the network schedule with identification of time parameters of volumes of repair of its separate nodes, and also to justify reserves allowing to accelerate carrying out planned repairs of traction engines in volume of TR-600 of the electric locomotive. The results obtained can be used in service locomotive depots when justifying measures to optimize the technological process of repair of electric locomotives in order to reduce the time and economic costs of repairing electric locomotives 2ES6.

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.
