Some treatment parameters led to boron carbon coating above the boride layer which ACTS as a diffusion barrier and prevents a further growth of the boride layer.

一些处理参数会导致在硼化物层上形成硼-碳层，它将起着扩散垒的作用，阻止了硼化物进一步的生长。

Results show that the bearing life is closely connected with the composition and appearance of the nickel-barrier layer and diffusion of the elements.

结果表明，轴瓦的寿命与镍栅层的成分，形貌和元素的扩散有着密切的关系。

The boundary layer flow control using dielectric barrier surface discharge plasma is simulated using Poisson's equation, drift-diffusion model and N-S equations.

使用泊松方程、漂移扩散模型和N—S方程对介质阻隔面放电等离子体控制边界层流动进行了一体化数值模拟。
