A device and a method for fabricating a ceramic reinforced composite coating based on plasma remelting and injection. The device includes a plasma cladding assembly, a powder feeding assembly, a metal-based substrate, and a thermal infrared imager. The plasma cladding assembly comprises a plasma gun and a plasma generator. A plasma arc generated is used to heat the substrate and form a molten pool on the substrate. The powder feeding assembly comprises a powder feeder configured to feed ceramic particles to the molten pool through a powder feeding copper tube. The thermal infrared imager is configured to acquire an infrared image of the molten pool and acquire an optimal injection position of the ceramic particles according to the infrared image. The optimal injection position is a midpoint between a trailing edge of the plasma arc emitted on the substrate and a trailing edge of the molten pool.
