A Review of Corrosion and Hydrogen Diffusion

the steel surface on corrosion and subsequent hydrogen diffusion behaviors is discussed. Moreover, the hydrogen diffusion behavior of the pipe steel under tensile stress in both elastic and plastic ranges is explored based on a number of hydrogen permeation test results. With the experimental demonstrations, numerous theoretical Behavior of Hydrogen in Steel During - CORROSION Online(2006) Hydrogen permeation through a slab sample in the case of high hydrogen concentration. Thin Solid Films 496 :2, 735-739. Online publication date:1-Feb-2006. Effect of Heat Treatment Conditions on Corrosion and Corrosion Science and Technology. Abstract:The purpose of this study was to examine the influence of conditions for quenching and/or tempering on the corrosion and hydrogen diffusion behavior of ultra-strong automotive steel in terms of the localized plastic strain related to the dislocation density, and the precipitation of iron carbide.

3.1. Hydrogen Permeation Behavior of Coated Steels. Figure 5 shows the changes in hydrogen permeation current and RH of (a) SZn and (b) SZnAl specimens during the wet and dry corrosion tests. There are periodic changes of the hydrogen permeation currents following the cyclic changes of RH with both specimens. Effect of interaction between corrosion film and H2S/CO2 The hydrogen permeation behaviour of X80 pipeline steel exposed to corrosion environments with different H 2 S/CO 2 partial pressure ratios at room temperature was investigated through the high-pressure electrochemical hydrogen permeation test. Both CO 2 and H 2 S have a hydrogen permeation promoting effect; however, CO 2 hydrogen permeation promoting effect is much Effects of Stress on Entry and Permeation of Hydrogen in Jul 01, 2017 · (2017) Effect of the elastic tensile load on the electrochemical corrosion behavior and diffusible hydrogen content of ferritic steel in acidic environment.

Hydrogen Permeability of Sintered Aluminum Oxide - Hydrogen permeability of highdensity, highpurity sintered alumina tubes was measures is a function of temperature and pressure using tritium as a tracer. The permeability, ø, at 1200° to 1450°C and hydrogen partial pressure between 2 and 50 kPa is:(H atoms cm cm 2 s

Hydrogen Permeation and Corrosion Fatigue Crack

(2018) Electrochemical corrosion, hydrogen permeation and stress corrosion cracking behavior of E690 steel in thiosulfate-containing artificial seawater. Corrosion Science 144, 145-162. Online publication date:1-Nov-2018. Hydrogen Permeation and Electrochemical Corrosion Behavior Apr 18, 2012 · The hydrogen permeation and electrochemical corrosion behavior were investigated by various electrochemical measurements and analysis. It was found that there is the smallest hydrogen permeation rate, but the largest hydrogen trapping density at heat-affected zone, while the base steel has the lowest hydrogen trapping. Hydrogen permeation behavior and corrosion monitoring And a clear linear correlation exists between the quantities of hydrogen permeated through the 16Mn steel and the weight loss. Based on the linear correlation, we monitored the corrosion rate by monitoring the hydrogen permeation current by a sensor outside. Good coherences were shown between results in laboratory and outside.
