Abstract

Selection of an optimal corrosion protection method for offshore structural high-strength steel was necessary to avoid potential fatigue and hydrogen embrittlement problems. A study to evaluate the corrosion protection provided by sacrificial anodes and flame-sprayed aluminum coatings was undertaken. Reliability, availability, and influence on fracture and fatigue properties were the main factors considered in the study. The results illustrated that a properly applied flame-sprayed aluminum (FSA) coating represents the most viable scheme for providing long-life corrosion protection and improved corrosion fatigue and cracking resistance.
