Abstract. The purpose of the research presented in the paper is to create the express-method for the estimation of the influence of the anticorrosive treatment made by surfactant compounds on aluminium alloys fatigue. As a material for the tests the aluminium alloy D16AT widely used in aviation industry has been selected. The method is based on the phenomenon of the initiation and development of the deformation relief on the surface of alclad alloys under the cyclical loading. The intensity of the relief indicates the accumulated fatigue damage. The analysis of the relief is provided by the computer aided optical method. The comparison of the deformation relief on the specimens covered by the inhibiting corrosion compounds with the surface relief of uncovered components gives the possibility to make conclusion about the influence of the covering on the fatigue process.
The influence of the surfactants on the metal fatigue can be observed and monitored on the initial stage of fatigue. The application of the method allows preventing negative side effects of the anticorrosive treatments, selecting the optimum compound for the protections.
Keywords: aluminium alloys, corrosion, surfactants, fatigue, deformation relief.
