Corrosion-resistant and wear-resistant ceramic bearing and preparation method thereof
The invention discloses a corrosion-resistant and wear-resistant ceramic bearing and a preparation method thereof. The corrosion-resistant and wear-resistant ceramic bearing comprises an outer ring, an inner ring, a ball and a retainer, wherein the ball is arranged between the outer ring and the inner ring, the outer ring and the inner ring are made of hot isostatic pressing ZrO2 ceramic, the ballis made of hot isostatic pressing ZrO2 reinforced Al2O3 ceramic, the retainer is arranged on the periphery of the ball and partially wraps the ball, and the retainer is made of polytetrafluoroethylene. The ceramic bearing prepared by the method has excellent corrosion resistance and wear resistance in an acid corrosion environment.
本发明公开一种耐腐蚀、耐磨损的陶瓷轴承及其制备方法。所述耐腐蚀、耐磨损的陶瓷轴承包括外环、内环、球滚珠、保持架；所述球滚珠在外环与内环之间设置，外环和内环由热等静压ZrO陶瓷制成，球滚珠是由热等静压ZrO增强AlO陶瓷制成，保持架在球滚珠的四周，部分地包裹球滚珠，保持架由聚四氟乙烯制成。该方法制备的陶瓷轴承在酸腐蚀性环境中具有优良的耐腐蚀和耐磨损性能。
