Method of producing areas of alloy metal on a metal part using electric currents

A method and apparatus for modifying the surface properties of a metal part in which electric current having a frequency of at least 3000 Hz is supplied to a narrow area on the part by means of contacts, one at each end of the area, and a proximity conductor or is induced therein by an induction coi...
