The invention discloses an electrolytic
machining method for maintaining and
remanufacturing of an aeroengine. The electrolytic
machining method for maintaining and
remanufacturing of the aeroengine comprises the first step of study on the electrolytic
machining mechanism of
titanium alloy, the second step of design and preparation of a
cathode, the third step of preparation of a special
electrolyte, the fourth step of acquisition of technological parameters in the electrolytic
machining process, the fifth step of study on precision control of electrolytic machining, the sixth step of study on the influence of flow field distribution of the
electrolyte, and the seventh step of establishment of an electrolytic machining quality
evaluation system. According to the electrolytic machining method for maintaining and
remanufacturing of the aeroengine, the electrolytic machining technique is used for replacing a traditional machining method to meet technical requirements for machining of molded surfaces of key components of the civil aeroengine, so that secondary damage such as micro-cracks, micro-scratches and generated mechanical stress, caused by the traditional machining method, to a
machined surface is avoided. The electrolytic machining method is used as the machining basis for welded
titanium alloy structural components, so that influences such as overheating, a cold working layer, mechanical stress and micro-damage to the surface can be avoided while a redundant surfacing layer is removed; and meanwhile, the influence of feeding limitation of the traditional machining method can be avoided, the
machining time is greatly shortened, and economic cost is reduced.
