| titleOfInvention | A kind of preparation method of powder metallurgy composite material for art |
| abstract | The invention discloses a preparation method of a powder metallurgy composite material for art. The inlaid body is placed in an alcohol solution to be degreasing and dried by an ultrasonic cleaning machine, and the inlaid body is divided into copper parts of different meshes according to a certain size and volume ratio. The matrix powder is arranged as a whole according to the needs of art manufacturing. The color of the mosaic body should be different from the color of the copper matrix powder, and sintered. After the sintering is completed, diffusion annealing is performed at a certain temperature to finally obtain a colorful composite material blank, and follow-up is carried out. Processed to form colorful composite finished products. Compared with the smelting and casting method, the invention has high yield and net final shape, and has beautiful and colorful color, shape and pattern compared with the conventional powder metallurgy production method. The preparation process of the invention is suitable for industrial production, and can be applied to the fields of art, commemorative seal, decoration and the like. |
