Microarc oxidation coated magnesium alloy radiator for light emitting diode: Microstructure, thermal radiative and dissipating property

High infrared emissivity value coatings on magnesium alloy radiator for Light-emitting diode (LED) were successfully fabricated by microarc oxidation (MAO) method aiming to enhance thermal dissipation. And different phase compositions of MAO coatings have an effect on infrared emissivity property at elevated temperature, which determines the dissipating property of MAO coated magnesium alloy radiator for LED.103
