A high-strength multi-functional coating with a multi-level structure, and a preparation method thereof are provided. In this application, a high-efficiency cladding method based on infrared laser-plasma synchronous compounding is adopted to prepare a micro-scale columnar crystal structure that is perpendicular to a substrate and serves as a pure thermally and electrically conductive channel, and to prepare submicro- and nano-scale ceramic reinforcement phases between columnar crystals, where the submicro- and nano-scale ceramic reinforcement phases are distributed along grain boundaries. The multi-level organizational structure of this application can simultaneously improve the hardness, wear resistance, and electrical and thermal conductivities of a cladding layer for a copper alloy and can improve the reliability of damage protection for a copper alloy component used in an extreme environment.
