Abstract
Process for producing an aluminum material having an aluminum nitride surface layer which comprises implanting the surface of an aluminum substrate with nitrogen ions while maintaining a nitrogen atmosphere under reduced pressure in the vicinity of the surface of the aluminum substrate. The aluminum nitride modified layer contains substantially no impurities such as oxygen. It is a feature of this invention to perform ion implantation in a properly controlled nitrogen atmosphere at a proper degree of vacuum in the range of about 10.sup.-7 to 10.sup.-5 Torr.
