Abstract
Use of aluminum alloys in vacuum machine building leads to a significant weight reduction in the articles, to improvement in operating conditions, and to a reduction in outlays for the treatment of components. One of the most inexpensive and universal methods of hardening the working surfaces of components formed from aluminum alloys is anodizing. The plasma-electrolytic method of anodizing, which produces the dense plasma near the metal at a low anode temperature, was developed on the basis of plasma theory. A characteristic feature of this method is that the specimen (anode) being oxidized is placed in the electrolyte, and the cathode is situated over it above the level of the electrolyte. An electric discharge develops between the electrode when a sufficient voltage is applied. The discharge can be initiated by different methods. For example, a drop of electrolyte is placed in the space beneath the cathode, or the level of the electrolyte is raised. In the process of oxide formation, the electrolyte rises and the space between the electrodes is filled with its vapors. As a result, the electrodes are heated negligibly (below 80 degree C under the conditions investigated). This paper describes the designing an apparatus to anodize components with an area of 2 dm super(2).
