Surface modification method of ZTA ceramic chopper material
The invention belongs to the technical field of ZTA ceramic materials, and particularly relates to a surface modification method of a ZTA ceramic chopper material. The modification method comprises the following specific modification steps: 1) degreasing a ZTA ceramic blank; (2) carrying out primary sintering on the ZTA ceramic blank; (3) injecting chromium ions; and 4) secondary sintering. Compared with the prior art, the preparation method has the technical advantages that the chromium ions are injected into the surface layer of the ZTA ceramic material, meanwhile, secondary sintering treatment is added, the chromium ions exist in the form of chromium oxide, the chromium oxide can smoothen defects in a ZTA ceramic crystal structure, meanwhile, reaction between ZTA ceramic and other substances is reduced, and the performance of the ZTA ceramic material is improved. And due to the characteristic of ion implantation, the thickness and distribution of chromic oxide on the surface layer of the ZTA ceramic material are more uniform, so that the consistency between different ZTA ceramic chopper products is better.
本发明属于ZTA陶瓷材料技术领域，具体涉及一种ZTA陶瓷劈刀材料的表面改性方法。该改性方法的具体改性步骤为：1）ZTA陶瓷胚件脱脂；2）ZTA陶瓷胚件一次烧结；3）铬离子注入；4）二次烧结。与现有技术相比，本发明的技术优点在于：本发明将铬离子注入到ZTA陶瓷材料表层，同时再增加二次烧结处理，将铬离子形成以氧化铬的形式存在，氧化铬可以顺化ZTA陶瓷晶体结构中的缺陷，同时减少ZTA陶瓷与其它物质之间的反应，从而提高ZTA陶瓷材料的耐磨性，由于离子注入的特性，ZTA陶瓷材料表层的氧化铬的厚度和分布更均匀，使得不同ZTA陶瓷劈刀产品之间的一致性更好。
