QUE SIGNIFIE HYDROGEN EMBRITTLEMENT EN ANGLAIS
Fragilisation de l'hydrogène
La fragilisation de l'hydrogène est le processus par lequel différents métaux, surtout l'acier à haute résistance, deviennent fragiles et se fracturent après l'exposition à l'hydrogène. La fragilisation de l'hydrogène est souvent le résultat d'une introduction involontaire d'hydrogène dans des métaux sensibles pendant les opérations de formage ou de finition et augmente la fissuration dans le matériau. Ce phénomène a d'abord été décrit en 1875. La fragilisation de l'hydrogène est également utilisée pour décrire la formation d'hydrure de zirconium et de craquage à l'hydrure différée. L'utilisation du terme dans ce contexte est courante dans l'industrie nucléaire.
définition de hydrogen embrittlement dans le dictionnaire anglais
La définition de la fragilisation par l'hydrogène dans le dictionnaire est l'affaiblissement du métal par la sorption de l'hydrogène au cours d'un processus de décapage, tel que celui utilisé dans le placage.
