Amplitude-modulated decomposition carbide powder for in-situ precipitation of nano WC and preparation method thereof
The invention belongs to the technical field of material preparation, and particularly relates to amplitude-modulated decomposition carbide powder for in-situ precipitation of nano WC and a preparation method of the amplitude-modulated decomposition carbide powder. Commercial TiO2, ZrO2, WO3 and graphite powder are used as raw materials, the fully mixed powder is subjected to carbonization reduction reaction through pressureless sintering, and (Ti, Zr, W) C ceramic powder is obtained; and then the carbide ceramic powder is subjected to aging treatment for 1-3 h at the temperature of 1200-1500 DEG C, and the carbide ceramic powder is obtained. The sample subjected to specific aging treatment has the phenomenon of coexistence of in-situ precipitation of WC nanoparticles and amplitude modulation decomposition, the process is simple and easy to control, the formation mechanism is clear and definite, and the method has high industrial application potential.
本发明属于材料制备技术领域，具体涉及一种原位析出纳米WC的调幅分解碳化物粉末及其制备方法。本发明以商业TiO2、ZrO2、WO3和石墨粉末为原料，充分混合后的粉末通过无压烧结进行碳化还原反应，得到(Ti,Zr,W)C陶瓷粉末；随后在1200‑1500℃下对所述碳化物陶瓷粉末进行1‑3h的时效处理即得。本发明经过特定时效处理后的样品出现了原位析出WC纳米颗粒与调幅分解共存的现象，工艺简单易控，形成机理明确清晰，有较高的工业应用潜力。
