The present application belongs to the technical field of mechanical cutting tool manufacturing, and particularly relates to a micro-textured tool based on laser micro-cladding in-situ forming, a preparation method and application thereof. Specifically, the present application successfully prepares a multi-layer coated tool with a micro-textured morphology. The tool has the advantages of micro-texture, laser cladding layer and multi-layer coating structure, and has high hardness, good self-lubricating performance, good toughness, strong coating adhesion and small internal stress of the coating, and will not produce defects such as deformation or micro-cracks of the tool substrate material. In the cutting process, the tool can effectively reduce the cutting force and cutting temperature, reduce tool wear and improve tool life, and can be widely applied to dry cutting and cutting of difficult-to-machine materials, and therefore has good practical application value.
