Surface-modified reaction-sintered silicon carbide ceramic and preparation process thereof
The invention relates to a surface-modified reaction-sintered silicon carbide ceramic and a preparation process thereof. The reaction-sintered silicon carbide ceramic is composed of F90 silicon carbide, F180 silicon carbide, F1200 silicon carbide, carbon black, a binder, a dispersant and deionized water. The preparation process comprises the steps of raw material mixing, material fermenting, sintering and surface nitriding. Free silicon on the surface of the reaction-sintered silicon carbide is reduced as much as possible, the performance of the reaction-sintered silicon carbide ceramic is improved, and the service life of the reaction-sintered silicon carbide ceramic is prolonged.
本发明涉及一种表面改性的反应烧结碳化硅陶瓷及制备工艺，反应烧结碳化硅陶瓷，由F90的碳化硅、F180的碳化硅、F1200的碳化硅、炭黑、粘结剂、分散剂以及去离子水组成；其制备工艺包括原料混合、醒料工艺、烧结工艺以及表面氮化工艺。本发明尽可能的减少了反应烧结碳化硅表面的游离硅，提高了反应烧结碳化硅陶瓷的性能和使用寿命。
