Understanding the failure mechanisms of coatings on contaminated steel substrates

The project will determine the method by which coatings on contaminated surfaces fail through the development of protocols for carrying out adhesion tests within a high vacuum environment so that the locus of failure may be fully characterised.

The protective nature of paints is impaired when the substrate is not suitably prepared. For structural steelwork, this problem has been traditionally dealt with by applying red lead, which acts to negate the effect of corroded surfaces. This treatment is no longer ecologically acceptable. Environmental concerns have prompted research to develop a better understanding of the mechanism by which coatings protect. This project would determine the method by which coatings on contaminated surfaces fail through the development of protocols for carrying out adhesion tests within a high vacuum environment so that the locus of failure may be fully characterised.
