Mathematical Models for the Corrosion Protective Performance of Organic Coatings (Classic Reprint) - Tapa dura
Sinopsis
Excerpt from Mathematical Models for the Corrosion Protective Performance of Organic Coatings
In order to assess the corrosion protective performance of organic coat ings the phenomena that lead to corrosion must be understood. Corrosion itself is the destruction of a metal surface by electrochemical action. Aqueous corrosion occurs when three things are present: oxygen, water and an electrolyte. There will be no corrosion unless all three are present at the corrosion site.
Figure 1 shows a cross-section of a typical organic coating. A coating having a uniform thickness L (typically mm) covers a metal substrate. The organic coating consists of a vehicle (or binder) phase and a particle (or pigment) phase. Water and oxygen can penetrate through the coating to the surface of the substrate. The rate of passage of the penetrants (water and oxygen) will depend on many factors: the availability at the coating surface, their solubility in the coating, their diffusivity through the coating, their affinity for the pigment particles their rate of consumption at the corrosion site and the osmotic pressure of the electrolyte-membrane combination. In addition to depending on the chemical and physical nature of the organic coating used, all of these factors are temperature sensitive.
