The surfaces of Al‐Co‐Ce bulk crystalline alloys have been successfully laser processed resulting in amorphous‐like surface layer formation with enhanced corrosion characteristics. The material system, Al 84 Co 7.5 Ce 8.5 , is one of several next generation alloy compositions scientifically designed to form a metallic glass under the proper processing conditions. This material system exhibits both local composition changes and enhanced corrosion resistance in comparison to their native counterparts.
