氫在金屬中的擴散和氫滲透

Hydrogen Diffusion and Permeation in Metals

摘要


本文簡要評述了近年來氫在金屬中的擴散和氫滲透方面的工作,介紹了氫在金屬中的擴散機制,對影響氫擴散的因素如溫度、應力、氫陷阱做了小結,特別討論了還有爭議的問題:如氫在位錯、晶界中的擴散、表面狀態的影響等等。

並列摘要


The present work critically reviewed hydrogen diffusion and permeation in metals. The roles of temperature, stress and traps in hydrogen diffusion and permeation are discussed. Especially, we focused on the controversial problems such as hydrogen diffusion along dislocations and grain boundaries, and the influence of the surface state on measurement of hydrogen diffusivities.
