Protecting aluminum from corrosion
Webbof corrosion protection studies focused on useful and economical coating methods [2-4]. Organic or inorganic barrier layers are generally applied to effectively control the corrosion rates of applied aluminum alloys, thus avoiding the occurrence of the cathode reaction [5]. Traditionally, corrosion WebbCorrosion of metals Rusting can be prevented by keeping oxygen and water away, and by sacrificial protection. An alloy is a mixture of elements, including at least one metal.
