AB The work describes the effect of the atmospheric corrosion upon the mechanical properties of blind rivets. The subject of given research is: corrosion of metal materials, system resistance, design modification and others means of prevention against the corrosion attack. The problem of blind rivets, blind rivet setting, setting equipment, terminology and definitions, characteristic, and special blind rivet setting is also analysed. The experiment itself, the experimental method and the evaluation of the test are described. Mechanism of riveted joint damage produced by galvanic corrosion is proposed. Considerable corrosion damage occurred at combination of the joint members and connected materials with different electrochemical potentials. Exposition to the corroding environment produces release of rivet clam, together with decrease of rivet stiffness. The proof of these mechanisms is documented by functional dependence F - ΔL and metallographic tests.
