stable diffusion

By carbon ion implantation, painting Ag slurry and electric plating Ni into/ on the surface of nanocrystalline copper, some stable diffusion sources are obtained, in which the atoms are interstitial or substitutional.

然后进行表面离子注入碳，表面涂覆银浆和电镀镍等处理，在纳米晶层内部或表面得到一定浓度的间隙或置换溶质原子，热处理后考察它们的扩散行为。
