Title: Method for making metal-nanostructured carbon composites

Abstract

A method for making covetic metal-nanostructured carbon composites or compositions is described herein. This method is advantageous, in that it provides substantially oxygen-free covetic materials and allows precise control of the composition of the covetic material to be produced. The method comprises introducing carbon into a molten metal in a heated reactor under low oxygen partial pressure, while passing an electric current through the molten metal. The reactor is heated at a temperature sufficient to form a network of nanostructured carbon within a matrix of the metal. After heating the covetic material is recovered from the reactor.
