Wasserstoffdiffusion

Diffusion in Festkörpern

Wasserstoffdiffusion

Wasserstoffdiffusion beschreibt den zeitabhängigen Transport von Wasserstoffatomen in Festkörpern entlang Konzentrations- und Potentialgradienten, beschrieben durch Fick’sche Gesetze und häufig gekoppelt an Fallenbildung und Versetzungsbewegung. Sie beeinflusst Wasserstoffversprödung, Permeation durch Membranen und die Leistung von Speicher- und Brennstoffzellwerkstoffen. Diffusionskoeffizienten sind stark temperatur-, Mikrostruktur- und Phasenabhängig.
