Effect of Thermal Treatments on the Localized Corrosion Behavior of Alloy 718 (UNS N07718)
What is the localized corrosion resistance of the Nickel alloy 718 (UNS N07718) in oxidizing chloride containing environments like seawater? This articles gives some clues.
Maximum allowable service temperatures and the ASTM G48 test
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.
Hydrogen diffusion control during stress corrosion cracking of magnesium alloy AZ31B in chloride solutions – Abstract
SCC of AZ31B alloy was studied in NaCl solutions at different potentials and chloride concentrations using the slow strain rate technique. A combination of pre-exposure tests followed by immediate straining or straining after a dry air exposure delay helped to weight the relative importance of anodic damage accumulation versus increased hydrogen charging during open-circuit potential pre-exposure. The dependence of ductility with pre-exposure time and the fracture surface of embrittled samples suggest that hydrogen embrittlement of AZ31B was controlled by hydrogen diffusion.
Selecting corrosion resistant alloys for seawater applications
This abstract has been submitted to the upcoming NACE International CORROSION/14 Research in Progress Session on Passivity and Localized Corrosion. By: Mariano Iannuzzi Coauthors: Mauricio Rincón-Ortiz (first author), Mariano Kappes, Martín A. Rodríguez, Ricardo Carranza, and Raúl Rebak. In the offshore oil and gas industry, materials selection philosophies are traditionally based on the International Standard Organization (ISO) 21457 […]
