Abstract
The invention belongs to the technical field of titaniumalloy composite metal preparation, particularly relates to a preparation method for metal injection molding of a titaniumalloycomposite material, and provides the following scheme now to solve the problems that traditional titaniumalloymetal materials are mainly subjected to die casting, stirring casting and other methods, but the methods are generally complex in process equipment, high in cost and poor in preparation quality. The preparation method comprises the following preparation steps that S1, raw materials are prepared and treated; S2, the raw materials are preheated and mixed; S3, smelting and impurity removal are performed; S4, injection molding is performed; S5, cooling and demolding are performed; S6, shape machining is performed; and S7, performance detection is performed; the raw materials in S1 include titanium powder, a binder, boroncarbidepowder, aluminum powder, magnesiumpowder, copper powder, nickel powder, carbon fiber powder and a modifier. The preparation method is easy and convenient to operate, adopts an injection mode, can realize integral forming, and reduces the preparation difficulty; various metals and fibers are added during preparation, so that the strength and toughness of the composite material can be improved.
