2017 Frank Newman Speller Award: Knowledge-Based Predictive Analytics in Corrosion
Abstract
Corrosion researchers have developed many approaches to predicting the occurrence of different corrosion modes. Four types of predictive analytics can be identified: data-centric correlative analysis, theory-based semi-empirical models, expert-knowledge-based models, and theory-based, multi-scale models. However, most new corrosion failures have been serendipitous discoveries, rather than anticipated through a systematic process. This paper reviews stress corrosion cracking (SCC) of carbon steel in non-aqueous electrolytes and in aqueous solutions of oxyanions, to understand whether using the appropriate predictive analytic strategy may have helped anticipate the failures. In all of these cases of SCC, some information was available in related environments prior to field failures, but a framework was lacking to identify the connections and anticipate failures. Data-centric predictive analytics would not have helped anticipate the failures because of the low frequency of the phenomena and the lack of prior...

The petrochemical industry is very interested in the sour service fatigue performance of girth welded steel pipes. As a result several papers are published every year addressing this issue, and several Joint Industry Projects (JIP) are currently underway addressing different aspects of sour service performance of steel pipelines. To date research work has focused on quantifying the fatigue performance via small scale specimens due to the difficult and danger in dealing with H2S. Currently a JIP ...

Corrosion processes mainly affect the probability of failure, which then leads to consequences, such as, fire, explosion, or environmental damage. This paper focuses on the use of Bayesian network models for assessing the probability of corrosion. The Bayesian network approach incorporates cause- effect relationships of complex systems in the form of conditional probabilities. This method considers both knowledge uncertainties (i.e., modeling uncertainties) and data uncertainties to make more in...

Abstract A collection of data documenting the stress corrosion cracking (SCC) behavior of austenitic stainless steels (SS) in high-temperature aqueous environments was investigated using empirical learning techniques. Computer-based empirical learning systems based on classical and nonparametric statistics, connectionist models, machine learning methods, and fuzzy logic are described. An original method for inducing fuzzy rules from input-output data is presented. Performance comparisons of the ...

AbstractThe nature of attack on unstressed iron and the mode of cracking in stressed iron during immersion in boiling Ca(NO3)2, NaNO3, NH4NO3 solutions and various mixed Ca2+ and NH4+ solutions have been followed by microscopic examination of specimens removed from the solutions at various fractions of the mean failure time and by stress-corrosion tests.Only NH4NO3 gives rise to intergranular trenching in the absence of stress, and this ability, together with severe pitting attack, leads to a mo...

Abstract The effects of the environmental factors, aqueous HCl, anhydrous HCl, and water, on stress corrosion cracking (SCC) and anodic polarization of annealed zirconium in methanol-HCl solutions have been studied and the corresponding correlations are brought out. The occurrence of minimum time to failure by SCC, corresponding to maximum susceptibility, at a concentration of 0.4 Vol% aqueous HCl has been shown to be due to the coexistence of active and passive states. The activating and passiv...

Abstract Corrosion pits have been shown to nucleate fatigue cracks, and this is a critical issue for aerospace aluminum alloys, which experience a variety of corrosive environments in service. Consequently, modeling pit growth as a function of environment is necessary. In this study, two orientations of AA7075-T651 blocks were boldly exposed in solutions of varying temperature, pH, and [Cl − ] for three exposure times. Optical profilometry and Weibull functions were utilized to characterize pit ...

A stochastic model previously developed by the authors using Markov chains has been improved in the light of new experimental evidence. The new model has been successfully applied to reproduce the time evolution of extreme pitting corrosion depths in low-carbon steel. The model is shown to provide a better physical understanding of the pitting process.

Abstract Stress corrosion cracking of Ti-8-1-1 alloy was studied using controlled potential techniques in aqueous and methanol environments with and without halogen ions. The alloy was observed to display susceptible zones in aqueous solutions containing halogen ions—susceptible zones are in the corrosion potential and pitting potential regions. Also, potential zones of anodic and cathodic protection exist. In methanol environments, the alloy displays both potential regions of cathodic protectio...

AbstractAbu Dhabi Company for Onshore Oil Operations operates multiple carbon steel oil flow lines, which are emplaced on the desert surface of Abu Dhabi. The company's main oil pipelines are buried with coating and cathodic protection and internally protected by chemical inhibition, but the flow lines are without coating and cathodic protection. Over the years, this approach has been successful for flow lines, but the frequency of corrosion related leaks has increased recently due to changing o...
