Known difficulty in obtaining oxide protective coatings electrochemically deliver large parts, when the use of traditional methods of PEO is difficult due to the need to have a bath of large volumes and powerful current sources, so you have to find different techniques. The need for such technologies arose in connection with the task to form a local oxide coating on the surfaces of large hull structures. In this article, to improve processing performance, describes the method of PEO and devices for its implementation, simplifying the design of the stand for oxidation, reducing the size of the stand and the volume of the electrolyte consumed, as well as the value of the required current, which provide a large range of parts from titanium alloys high quality of the oxide layer. The task is achieved by the fact that in this method several electrodes are used, which move over the entire surface of the part, or in the necessary places providing local oxidation. At the same time, the value of the consumed current is significantly reduced, since the PEO process takes place on a small area under the moved electrode and simplifies the cooling of the electrolyte.
