Method of removing oxide on a metal surface

An object bearing an oxide on the surface of a parent metal is immersed in a liquid containing a complexing agent. To prevent erosion of the parent metal by the liquid, electrons having energy levels on the base side with respect to the Fermi level of the oxide are generated outside the parent mater...
