The Corrosion Inhibitor Availability Model as defined in 2000 (CIAM 2000) presents a simplified binary approach to corrosion inhibitor performance. In particular, the corrosion inhibitor is assumed to be active and fully effective from the instant it is injected to the instant it no longer injected. As a consequence, the CIAM 2000 does not account for the transient performance of the corrosion inhibitor namely, the time required to reach steady state and the time required for the inhibitor to desorb or persistency. In the following paper Langmuir adsorption kinetics are utilized to analyze the corrosion inhibitor performance curve and based on the adsorption and desorption rate constants the CIAM 2000 is updated to better account for the short
term/transient response of the corrosion inhibitor. In particular, an attempt is made to better define and quantify "persistency" of the corrosion inhibitor in terms of desorptipn rate constant and the surface residence time.
