ABSTRACT:
A lubricant for forming a ferrous metal blank into a preselected configuration by warm- or hot-forming procedures. The lubricant is an alkali-modified borate glass containing a minor mole percent of an alkali metal oxide, preferably sodium oxide. The glass is formed in situ on the surface to be lubricated by depositing on the surface a glass-forming mixture of a source of boron oxide and an alkali metal borate and then heating the mixture to form the glass.
