Abstract: The present subject matter relates to techniques of electrolytic oxidation for composite materials. In an example, a method includes immersing a composite material into an electrolytic solution for electrolytic oxidation, wherein the composite material comprises a metal alloy substrate and a second substrate. The method further includes providing a predetermined voltage to the electrolytic solution after every predefined time interval, wherein the voltage triggers electrolytic oxidation of the metal alloy substrate.
