Ultrafast controllable strengthening method of alumina-based composite ceramic
The invention relates to an ultra-fast controllable strengthening method for alumina-based composite ceramics, which comprises the following steps: carrying out high-temperature treatment on A < l2O3 >-Al < N > composite ceramics by utilizing an electromagnetic field auxiliary heating technology, and realizing ultra-fast heating and cooling of an Al < 2O3 >-Al < N > composite ceramic sample through a dielectric coupling principle. The time of the oxidation reaction process can be greatly saved by ultra-fast heating and cooling, and the energy loss is reduced; meanwhile, by means of the electromagnetic field activation principle, the surface oxidation reaction process is accelerated, the oxidation heat preservation time is shortened, and a gradient oxidation layer structure is formed. In the electromagnetic field-assisted ultra-fast gradient oxidation process, in-situ monitoring of sample temperature and deformation is carried out through a temperature measuring device and an image acquisition device, real-time data acquisition and analysis of gradient oxidation starting and ending temperatures and oxidation expansion of the sample are realized, and finally, the gradient oxidation and lamination stress strengthening process and effect are accurately controlled.
本发明涉及一种氧化铝基复相陶瓷的超快速可控强化方法，其中，本发明的氧化铝基复相陶瓷的超快速可控强化方法利用电磁场辅助加热技术对A l2O3‑Al N复相陶瓷进行高温处理，通过介电耦合原理实现Al 2O3‑Al N复相陶瓷样品的超快速升温和降温，超快速升温与降温能够大大节约氧化反应过程时间、减少能量损耗；同时借助电磁场活化原理，加速表面氧化反应过程，缩短氧化保温时间，以形成梯度氧化层结构。在电磁场辅助超快速梯度氧化过程中，通过温度测量装置和图像采集装置进行样品温度与形变的原位监测，实现对样品梯度氧化起止温度与氧化膨胀的实时数据采集与分析，最终精准控制梯度氧化及层合应力强化的过程及效果。
