Questions about the asperity interaction between Fe and Al

Please reply to the list, not to me.

Your 2 figs make it look like the Fe/Al interaction

is repulsive at distance A, then becomes attractive

and the 2 surfaces snap together at distance B.

That would have to be due to the potential for the

cross-element interactions.

Hi dear all:
  I would like to ask that is there any research report about the cross-element interactions? I have not found so far.
