▎ 摘　　要

NOVELTY - Surface treatment method of metal plate comprises paving the powder of the surface reinforcing material on the metal plate or paving multiple sheet material on the metal plate, covering the cover plate, placing the explosive on the cover plate, removing the cover plate after detonating the explosive, where the sheet-shaped material comprises a sheet-shaped pressed body and/or a sintered body of the surface reinforcing material powder. USE - The method is useful for surface treatment of metal plate. ADVANTAGE - The method ensures that the size of the metal plate can be infinite and arbitrarily adjusts the composition and dosage of the surface reinforcing material powder and sheet material.
