The present disclosure provides a high-pressure and multi-atmosphere assisted SLM gradient material preparation method and an aluminum-lithium alloy coating. The high-pressure and multi-atmosphere assisted SLM gradient material preparation method includes the following steps: injecting a first gas mixture into a working box, and enabling, by laser irradiation, molten materials in a micro-melt pool to react with a carbon-containing gas to form a carbide-doped first gradient aluminum-lithium alloy coating; injecting a second gas mixture into the working box, and enabling, by laser irradiation, molten materials in a micro-melt pool to react with a carbon and nitrogen-containing gas to form a carbide and nitride-doped second gradient aluminum-lithium alloy coating; and injecting a third gas mixture into the working box, and enabling, by laser irradiation, molten materials in a micro-melt pool to react with a nitrogen-containing gas to form a nitride-doped third gradient aluminum-lithium alloy coating. The present disclosure improves the surface forming quality of an aluminum-lithium alloy material, and the material is hard outside and tough inside.
