Electrode materials based on a Ti–Al–C MAX phase

Abstract

Long-length electrode materials based on Ti–Al–C MAX phases have been produced by self-propagating high-temperature synthesis (SHS) in combination with extrusion and their structure and performance parameters have been studied. The results demonstrate that, varying the composition of the starting mixture and parameters of the SHS extrusion process, one can obtain materials based on the MAX phases Ti₃AlC₂ and Ti₂AlC and containing intermetallic and carbide inclusions or free of carbide components. Using the SHS extrusion process, we have produced MAX phase-based rods up to 10 mm in diameter and 350 mm in length, ranging in porosity from 2 to 16%.
