Hello, please can you tell me how to determine the surface diffusion coefficient for a particular crystallographic plane (e.g. {210} in bcc). It would be sufficient relatively with respect to other plane e.g. {100} - lets say the diffusion in this plane is two times higher than in this one.
And additionally can it be influenced by the fact that this is not pure metal but a solid solution (even if they are of the same lattice type). Or can such values be found somewhere in a literature? I have found it just for few elements and for only a few types of planes.
maybe this will help you

For your second question: Yes, diffusion is influenced by certain elements. In the case of plasma nitriding in stainless steels, it is known that nitrogen diffusion works out (is faster) over the chromium atoms in the alloy matrix. Also if no precipitations are formed. There is some literature about that.
