Composite ceramic coating material as well as preparation method and application thereof
The invention relates to a composite ceramic coating material as well as a preparation method and application thereof. The composite ceramic coating material comprises a carbon/carbon green body, pores are formed in the carbon/carbon green body, nano SiC-ZrC ceramic composite coatings are arranged on the outer surface of the carbon/carbon green body and the surfaces of the internal pores, and a micron SiC-ZrC ceramic composite coating is further arranged on the surface of the nano SiC-ZrC ceramic composite coating on the outer surface. And excellent silicification corrosion resistance and oxidation resistance are achieved. The invention also provides a preparation method of the composite ceramic coating and a crucible edge prepared from the composite ceramic coating material.
本发明涉及一种复合陶瓷涂层材料及其制备方法和应用。根据本发明的复合陶瓷涂层材料，包括碳/碳坯体，所述碳/碳坯体内部具有孔隙，碳/碳坯体的外表面以及内部孔隙表面均设有纳米SiC‑ZrC陶瓷复合涂层，外表面的纳米SiC‑ZrC陶瓷复合涂层表面还设有微米SiC‑ZrC陶瓷复合涂层，具有优良的抗硅化腐蚀和抗氧化性能。本发明还提供了上述复合陶瓷涂层的制备方法，以及由上述复合陶瓷涂层材料制备的埚邦。
