| titleOfInvention | A kind of forming method of Metal Substrate functional gradient composite materials |
| abstract | The invention discloses a kind of forming methods of Metal Substrate functional gradient composite materials, after first mixing additive with powder raw material, obtain mixture；Then the mixture that above-mentioned steps obtain is put into composite die group, after carrying out composite pressure molding, obtains blank；The composite die group includes outer layer high expansion coefficient mold, intermediate layer set of molds and internal layer low-expansion coefficient mold；Finally by above-mentioned blank after oversintering, Metal Substrate functional gradient composite materials are obtained.The present invention is prepared for the metal-based gradient functional composite material of the multicomponent without sharp interface with large scale, complex appearance structure.Gradient function composite material through-thickness after sinter molding obtains the gradient grain structure without sharp interface with different component, various grain sizes, and molding metal-base composites is made to obtain the preferable comprehensive mechanical performance in conjunction with high rigidity, wearability, intensity and toughness. |
