Silicon nitride-based ceramic ball as well as preparation method and application thereof
The invention discloses a silicon nitride-based ceramic ball as well as a preparation method and application thereof. The silicon nitride-based ceramic ball is formed by depositing a silicon carbide layer on the surface of a silicon nitride ceramic ball. Compared with a silicon nitride ball without a silicon carbide layer deposited, the disclosed silicon nitride-based ceramic ball is not prone tocorrosion and weightlessness in strong acid, strong alkali and kinematic friction states, meanwhile, an interface in contact with the strong acid and strong alkali environment is compact pure siliconcarbide and free of sintering aids, and the silicon nitride-based ceramic ball has better wear resistance, corrosion resistance and the like and can be applied to the field of wear-resistant bearings.
本发明公开了一种氮化硅基陶瓷球及其制备方法和应用，所述的氮化硅基陶瓷球为在氮化硅陶瓷球表面沉积一层碳化硅层。本发明的氮化硅基陶瓷球，与未沉积碳化硅层的氮化硅球相比，在强酸强碱且运动摩擦的状态下，不容易腐蚀失重，同时与强酸强碱环境接触的界面是致密的纯碳化硅，没有助烧剂，该氮化硅基陶瓷球具有更好的耐磨、耐腐蚀等性能，可应用于耐磨轴承领域应用。
