Silicon carbide-diamond composite powder for 3D printing as well as preparation method and application of silicon carbide-diamond composite powder
The invention discloses silicon carbide-diamond composite powder for 3D printing and a preparation method and application of the silicon carbide-diamond composite powder, and belongs to the technical field of advanced ceramic materials. The preparation method comprises the following steps: firstly, mixing diamond with a phenolic resin solution, uniformly stirring and mixing for a long time under a low-speed condition, heating into paste, and further heating in vacuum to obtain phenolic resin coated diamond; and uniformly mixing silicon carbide with the phenolic resin coated diamond according to the ratio, and further homogenizing the obtained mixture to obtain the silicon carbide-diamond composite powder for 3D printing. The prepared silicon carbide-diamond composite powder can meet the requirement of binder jet printing, and a densified silicon carbide-diamond composite component with a complex shape is obtained by adopting a liquid phase siliconizing mode at low temperature.
本发明公开了一种3D打印用碳化硅‑金刚石复合粉体及其制备方法和应用，属于先进陶瓷材料技术领域。本发明先将金刚石与酚醛树脂溶液混合，在低速条件下长时间搅拌混匀，加热成糊状，再进一步真空加热，得到酚醛树脂包覆的金刚石；然后按配比将碳化硅与酚醛树脂包覆的金刚石混匀，将所得混合物进一步均质，得到所述的3D打印用碳化硅‑金刚石复合粉体。本发明制备的碳化硅‑金刚石复合粉体可以满足粘结剂喷射打印的要求，在低温下采用液相渗硅方式得到复杂形状、致密化的碳化硅‑金刚石复合材料部件。
