What is Reliability Analysis for Degradation Effects of Pitting Corrosion in Carbon Steel Pipes about?

Corrosion is a major cause of failure in some metals with adverse effects on reliability of components and structures made from such metals. For example in carbon steel pipes various forms of localized corrosion, pitting corrosion, and stress corrosion cracking (SCC) cause sudden and catastrophic failures due to the absence of any external sign of damage in the system. Studying the growth of pit depth and pit densities at different temperatures and stress conditions with respect to time is critical in monitoring the localized corrosion damage and preventing the system downtime. A new probabilistic physics-of-failure (PPOF) model is developed to determine the temperature and stress dependencies of pit depth growth with respect to time. In doing so, microscopic methods are used to determine the pit depths produced on X-70 carbon steel samples subjected to accelerated corrosion tests. The pit depths and densities are measured in unstressed and stressed samples exposed to a solution of Sodium thiosulfate and water at different times and temperatures to ascertain the temperature and stress dependencies of pit depths that propagate during the pitting corrosion process. The stress and tem
