Hydrogen embrittlement of Zn-, ZnNi-, and Cd-coated

Jan 20, 2013 · Sacrificial coatings, such as Zn and Cd, are used to protect steel against corrosion. During the electrodeposition of metals, hydrogen is evolved due to electrolysis. The evolved hydrogen may diffuse outward and become trapped in the substrate/coating interface or migrate inward into the steel lattice causing delayed embrittlement when the component is subjected to stress.Hydrogen embrittlement risk in cold-drawn stainless steels ifi 142 1997 hydrogen embrittlement riskMar 01, 2013 · The way in which an atom of H locates inside the Fe C structure of the steel also has an influence on the risk of embrittlement of steel. Different positions of H-atoms can be listed as follows: 1) absorbed-H (reversible diffusion), 2) trapped-H in the defects present in the microstructure of the steel (grain boundaries, dislocations, etc.) and ifi 142 1997 hydrogen embrittlement riskEvaluating risk of hydrogen embrittlementAlongside the hydrogen which is introduced during the welding process, previously existing hydrogen in the steel is loosened up by the welding heat and rendered movable and diffusible. »The special feature of this new method is that it also takes into account the effect of so-called hydrogen

Embrittlement | Fastenal

Hydrogen embrittlement (HE) is defined by ASTM F2078 as a permanent loss of ductility in a metal or alloy caused by hydrogen in combination with stress, either externally applied or internal residual stress.
