The history of NACE MR-0175, ISO 15156, and the 1% nickel limit – Timeline
This blog entry presents the development of the NACE MR-0175 in a historical perspective alongside research advancements in physical metallurgy and sulfide stress cracking.
Distributed sacrificial anodes, or how to save 500 tons in subsea production systems – Presentation
This presentation gave at CORROSION 2017, introduces the concept of cathodic protection by distributed sacrificial anodes (DSA), a promising new approach to optimizing external corrosion protection..
Hydrogen Embrittlement of Industrial Components: Prediction, Prevention, and Models – Publication
Hydrogen embrittlement is a common, dangerous, and poorly understood cause of failure in many metal alloys. This article presents a model based on the correlation of mechanical properties to scanning electron microscopy fractography analysis of fracture surfaces in the presence of simultaneously active hydrogen embrittlement micro-mechanisms.
Is sulfide stress cracking an anodic or a cathodic process?
Is sulfide stress cracking an anodic or a cathodic process? Does hydrogen play a role or is SSC controlled by anodic dissolution? Find out in this post!
Use of the critical acidification model to estimate critical localized corrosion potentials of duplex stainless steels – Publication
Can we use Galvele’s critical acidification model to estimate the localized corrosion resistance of engineering stainless steels?
Short answer: yes; long answer: it is complicated.
