boundary diffusion

基本解释

Grain sliding controlled by grain boundary diffusion is the main mechanism for low temperature superplastic behavior.
晶界扩散控制晶界滑动是低温超塑行为的主要机理。
The adsorption process followed the pseudo-second order model and intraparticle diffusion and boundary diffusion control the adsorption together.
动力学实验表明，吸附反应遵循准二级动力学模型，且粒内扩散和边界层扩散共同控制吸附过程。
Diffusion of oxygen in the bonding coating and substrate is mainly grain-boundary diffusion. Grain-boundary diffusion coefficient is far greater than intragrain diffusion.
氧在粘结底层和基体中的扩散是以晶界扩散为主，晶界扩散系数远远大于晶内的扩散系数。
