Localized corrosion risk assessment using Markov analysis

November 29, 2014 by Mariano Iannuzzi

The objective of this work was to develop the foundation for an interactive corrosion risk management tool, based on Markov Analysis, for assessing the probability of failure of industrial components as a function of threats (such as pitting corrosion and coating degradation) and mitigation schemes (such as inhibitors and coatings). doi: 10.5006/1184

Maximum allowable service temperatures and the ASTM G48 test

November 29, 2013 by Mariano Iannuzzi

Can we use the ASTM G48 test to establish the maximum allowable temperature of a metal or alloy in an oxidizing environment like seawater?
This post discusses how the ferric chloride electrolyte of the ASTM G48 test compares with other oxidizing environments such as seawater.
