Preparation method of composite microporous multi-structure bionic artificial bone, and gradient mold
The invention discloses a preparation method of a composite microporous multi-structure bionic artificial bone, and a gradient mold. The preparation method comprises the following steps: 1) preparing inner-layer mixed powder; 2) preparing a complex; 3) adding powder material for being filled in a sleeve in a layered mode, enabling each layer of sample to be provided with a corresponding pressing head, and pressing each layer of pressing head on the powder material; pressing the mold on a press machine to form a green body; and demolding from the mold to obtain a bionic multi-structure material blank; and 4) sintering the obtained blank in a vacuum furnace to remove the pore forming agent, and performing furnace cooling to obtain the gradient porous ceramic material A base is arranged at one end of the sleeve of the gradient mold, the other end of the sleeve is sleeved with the outer-layer pressing head, and the inner-layer pressing head is sleeved with the inner cavity of the outer-layer pressing head, the structure is simple, operation is convenient and easy, the preparation period is short, and the manufacturing cost is low.
复合微孔多结构仿生人工骨的制备方法及梯度模具，步骤为：1），内层混合粉体的制备；2），复合体的制备；3），套筒内所填充的粉体材料为分层加入的，且每层样品都有其对应的压头，每层压头均压制在该层粉体材料上；将模具在压力机上压制坯体；磨具脱模，获得仿生多结构材料坯体；4），将获得的坯体在真空炉内去除造孔剂烧结，随炉冷却获得梯度多孔陶瓷材料；梯度模具的套筒的一端设有底座；套筒的另一端套入外层压头，外层压头的内腔中套入内层压头；结构简单，方便易操作，制备周期短，制造成本低。
