Low-cost color-adjustable high-strength ceramic guide ring and preparation method thereof
The invention discloses a low-cost color-adjustable high-strength ceramic guide ring and a preparation method thereof.The low-cost color-adjustable high-strength ceramic guide ring is composed of zirconium dioxide particles, silicon oxide particles, yttrium oxide particles and modified and color-adjustable metal oxide particles, and the zirconium dioxide/zirconium silicate composite ceramic guide ring is obtained through slurry preparation, spray granulation, compression molding, low-temperature sintering and fluid polishing; wherein the zirconium dioxide particles account for 60-82 wt%, the silicon oxide particles account for 5-25 wt%, the yttrium oxide particles account for 4-12 wt%, and the modified and toning metal oxide particles account for 7-15 wt%; wherein the modified and toned metal oxides are three or more than three of aluminum oxide, iron oxide, cobalt oxide, chromium oxide and manganese oxide. According to the method, the low-cost oxide ceramic particles are used as raw materials, the high-strength, high-toughness and high-wear-resistance ultrathin ceramic guide rings with different colors are prepared at low temperature by doping different modified and toning metal oxides, and the method is simple in process, low in cost and easy to realize continuous industrial production.
本发明公开了一种低成本颜色可调高强陶瓷导环及其制备方法，由二氧化锆颗粒、氧化硅颗粒、氧化钇颗粒和改性及调色金属氧化物颗粒构成，经浆料制备、喷雾造粒、模压成型、低温烧结及流体抛光得到二氧化锆/硅酸锆复合陶瓷导环；其中，二氧化锆颗粒占60～82wt％，氧化硅颗粒占5～25wt％，氧化钇颗粒占4～12wt％，改性及调色金属氧化物颗粒占7～15wt％；其中，改性与调色金属氧化物为氧化铝、氧化铁、氧化钴、氧化铬和氧化锰中的三种或三种以上。本发明以低成本氧化物陶瓷颗粒为原料，通过掺杂不同改性与调色金属氧化物实现低温制备不同颜色的高强度高韧性高耐磨超薄陶瓷导环，本发明工艺简单、成本低，易于实现连续化工业化生产。
