Abstract
In this thesis, a one dimensional model is developed to investigate the initial stages of corrosion in a fastener assembly consisting of a stainless steel fastener and aluminum 7075 as the plate. Di fferential equations are formulated and solved to determine the pro files for the potential, the oxygen concentration, and the aluminum ion concentration in the crevice, and also the potential in the bulk electrolyte. This fastener system exhibits galvanic corrosion, pitting corrosion, and crevice corrosion. It is found that the potential decreases monotonically down the length of the crevice, the oxygen concentration decreases exponentially down the length of the crevice, and the aluminum ion concentration builds up away from the mouth of the crevice. It is conjectured that the location of maximum aluminum ion concentration is where the most severe corrosion will occur. A parameter study is also done to study the effect of changes to the di ffusivity, crevice width, and other parameters on the model calculations.
