High-temperature-resistant erosion-wear-resistant silicon carbide-zirconium dioxide gradient structure ceramic, preparation method and application
The invention discloses high-temperature-resistant anti-erosive wear silicon carbide-zirconium dioxide gradient structure ceramic, a preparation method and application, and belongs to the technical field of ceramic materials.The preparation method comprises the following steps that 1, a material system composed of silicon carbide, zirconium oxide and a binder is evenly mixed, plasticized and granulated through a double-screw extruder, and a mixture is obtained; then performing wire drawing through a single-screw extruder to obtain a composite wire material; (2) printing the composite wire material by FDM-3D printing equipment to obtain a ceramic blank with a gradient structure; (3) performing low-temperature degreasing on the ceramic blank with the gradient structure in an acetone bath, and then transferring the ceramic blank to a high-temperature atmosphere for degreasing; and (4) carrying out high-temperature calcination treatment on the degreased ceramic blank with the gradient structure, so as to obtain the high-temperature-resistant and erosive-wear-resistant SiC-ZrO2 ceramic with the gradient structure. The SiC-ZrO2 gradient structure ceramic prepared by the method provided by the invention has good high temperature resistance and erosion and wear resistance.
本发明公开了一种耐高温抗冲蚀磨损碳化硅‑二氧化锆梯度结构陶瓷、制备方法和应用，属于陶瓷材料技术领域，制备方法包括以下步骤：(1)将碳化硅、氧化锆和粘结剂组成的材料体系均匀混合，再经过双螺杆挤出机塑化并造粒，然后通过单螺杆挤出机拉丝，得到复合丝材；(2)将复合丝材利用FDM‑3D打印设备打印得到梯度结构陶瓷胚体；(3)将梯度结构陶瓷胚体在丙酮浴中低温脱脂后，再转移至高温气氛下脱脂；(4)对脱脂后的梯度结构陶瓷胚体进行高温煅烧处理，得到耐高温抗冲蚀磨损SiC‑ZrO2梯度结构陶瓷。本发明方法制备得到的SiC‑ZrO2梯度结构陶瓷具有良好的耐高温、抗冲蚀磨损性能。
