In general, diffusion coefficient is greater through less restrictive structural regions [1]. For instance, the diffusion coefficient through surface is greater than that through grain boundary, while it is greater through grain boundary than through single crystal as indicated in Figure 3230.

Self-diffusion coefficients for silver depend on the diffusion path
