Abstract
Disclosed herein is a method of selectively boronizing of the surface of ferrous metal that is characterized by applying to such area as is not to be boronized a coating consisting essentially of finely divided titanium dioxide, finely divided carbonaceous material and an anhydrous binding agent in effective amounts to form a boronizing resist having boronizing resistance during boronizing, then boronizing the ferrous metals at a temperature at which the coating forms the boronizing resist and subsequently removing the boronizing resist. Also disclosed are compositions for preferred applications of the coating and additional details on preferred embodiments.
