Abstract

Despite the increased interest of designers to composite polymer materials (PCM), aluminum alloys are still the basic constructional material of the aviation industry, therefore the questions of their corrosion protection, delivering special properties to their surface remain relevant. Modern ecological regulations of technological processes safety require to exclude application in toxic solutions for surface treatment such as hexavalent chromium. Technological solutions on preparation of aluminum alloys surface for pasting in the solutions which are not containing toxic compounds are provided in the work. The work is executed within the frames of the complex scientific direction 17.1. «Ecologically safe plasma electrolytic coatings for light alloys» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
