Abstract

By certification of aluminium alloys the investigation of their liability to isolated types of corrosion determined in laboratory conditions is obligatory as well as investigation of corrosion resistance of materials determined in the course of full-scale exposition. Regularly environmental tests of aluminium alloys are carried out under the conditions of open areas. This paper shows that investigations under the roof are more significant for the given class of materials as they provide amplification of monitoring factors of corrosive process – damping duration of the surface and expansion in the number of chlorides. Also this paper throws light on correlation problems of laboratory and full-scale corrosion testing and presents the procedure of full-scale accelerated tests allowing to reduce the time of environmental tests by 4–5 times in comparison with the exposition under full-scale conditions.
