Additive manufacturing method of modified diamond reinforced cordierite ceramic-based composite material
The invention discloses an additive manufacturing method of a modified diamond reinforced cordierite ceramic-based composite material, which utilizes the characteristics that cordierite is low in melting point and can be converted into a liquid phase in an SLM printing process, and improves the wettability of diamond particles and a cordierite ceramic matrix by performing surface modification on the diamond particles, so that the composite material has the advantages that the wear resistance of the composite material is improved, and the service life of the composite material is prolonged. The diamond particles and the cordierite ceramic matrix can form tight metallurgical bonding, meanwhile, the thermal damage phenomenon of the diamond is avoided, the densification degree of the diamond-cordierite composite material is improved, and the mechanical property of a diamond-cordierite composite material SLM printing piece is improved.
本申请公开了改性金刚石增强堇青石陶瓷基复合材料的增材制造方法，利用堇青石熔点低，能够在SLM打印过程中转变为液相的特点，通过对金刚石颗粒进行表面改性，提升金刚石颗粒与堇青石陶瓷基体的润湿性，使得金刚石颗粒与堇青石陶瓷基体能够形成紧密的冶金结合，同时避免了金刚石的热损伤现象发生，提高了金刚石‑堇青石复合材料的致密化程度，提升了金刚石‑堇青石复合材料SLM打印件的力学性能。
