Amplitude-modulated decomposition-hardening compound carbide ceramic and preparation method thereof
The invention discloses amplitude-modulated decomposition-hardening compound carbide ceramic and a preparation method thereof, and belongs to the technical field of ceramic materials. The compound carbide ceramic provided by the invention takes a transition metal source titanium source and a transition metal source zirconium source or a transition metal source titanium source, a transition metal source zirconium source and a transition metal source hafnium source as raw materials, compound carbide powder is prepared through a sol-gel method and heat treatment firstly, then the compound carbide powder is subjected to rapid hot pressed sintering, and a compound carbide ceramic block material is obtained; and carrying out aging treatment on the composite carbide ceramic block material at 1350-1450 DEG C for 2-4 hours to obtain the composite carbide ceramic block material. The sample subjected to specific aging treatment has an amplitude modulation decomposition phenomenon, and along with the generation of the phenomenon, the hardness is remarkably improved; meanwhile, the technological process is simple and easy to control, the forming mechanism is clear and definite, and the industrial application potential is very high.
本发明公开了一种调幅分解硬化复式碳化物陶瓷及其制备方法，属于陶瓷材料技术领域。本发明提供的复式碳化物陶瓷以过渡金属源钛源和锆源或钛源、锆源和铪源为原料，首先通过溶胶凝胶法和热处理制备复式碳化物粉末，然后将所述复式碳化物粉末进行快速热压烧结，得到复式碳化物陶瓷块体材料；在1350～1450℃下对所述复式碳化物陶瓷块体材料进行时效处理2～4h，即得。本发明经过特定时效处理之后的样品出现了调幅分解的现象，且伴随着这种现象的产生，硬度得到了显著提升；同时工艺过程简单易控，形成机理清晰明确，有很高的工业应用潜力。
