一种多层壳芯复合结构零件的制备方法
摘要：
本发明公开了一种多层壳芯复合结构零件的制备方法，包括下列步骤：(1)分别配制芯层、过渡层和壳层的注射成形用喂料；芯层和壳层喂料中的粉末选自金属粉末、陶瓷粉末或增韧陶瓷粉末中的一种或多种的混合物，且两者不相同，过渡层喂料中的粉末为梯度复合材料粉末；(2)采用粉末注射成形方法分别逐层制作多层壳芯复合结构零件的生坯；(3)对生坯进行脱脂处理；(4)对生坯进行烧结，获得所述多层壳芯复合结构零件。本发明通过采用粉末注射成形方法，制备获得了多层壳芯复合结构的零件，零件表面硬度高、耐磨，壳层厚度均匀，性能稳定持久，壳层和芯层经过渡层结合，结合力强，整体抗弯强度好，冲击韧性好，不易开裂。
摘要（英）：

A manufacturing method of a multilayer shell-core composite structural component comprises the following procedures: (1) respectively preparing feeding material for injection forming of a core layer, a buffer layer and a shell layer, wherein the powders of feeding material of the core layer and the shell layer are selected from one or more of metallic powder, ceramic powder or toughening ceramic powder, and are different from each other, and the powder of feeding material of the buffer layer is gradient composite material powder; (2) layer by layer producing the blank of multilayer shell-core composite structural component by powder injection molding; (3) degreasing the blank; (4) sintering the blank to obtain the multilayer shell-core composite structural component. The multilayer shell-core composite structural component has the advantages of high surface hardness, abrasion resistance, uniform thickness of the shell layer, stable and persistent performance.
