Corrosion is deterioration of essential properties in a material due to reactions with its surroundings. An organic coating is frequently deposited on the top of the metallic coating in order to generate a corrosion resistant system by taking advantage of the good properties of the sublayer. In corrosion protection, the coatings are desired to have low permeability, good environmental stability, ease of synthesis and low cost. This book examines the work related to organic film growth on the cathode, reviewing the influence of deposition parameters on the cataphoretic deposition process and on the protective properties of the obtained coatings. The state and applications of organosilanes in the protection of easily oxidised metals such as aluminum, steel and copper, among others are also reviewed. Due to the technological importance of iron and ferrous alloys, there is great interest in finding new surface coatings to improve their corrosion protection. This book reports on the experimental data obtained from the evaluation of the corrosion protection performance of different materials and coatings such as stainless steel, mild steel, shape memory alloys and Diamond-Like-Carbon coatings. Furthermore, the synthesis, structural properties, stability of a conducting polymer film has crucial importance in aspect of its corrosion protection efficiency. This book reviews the synthesis techniques, porosity and its importance, evaluation of corrosion performance, the problems faced with the use of conducting polymer films and the solutions to improve for coatings quality.
