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.
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 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? Does hydrogen play a role or is SSC controlled by anodic dissolution? Find out in this post!
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.
