Zirconia-toughened alumina ceramics, a particle size composition of the main component of alumina in the preparation of ceramic cylinder liners for drilling pumps, with an average particle size of 60-70 wt% in the range of 0.8-1.0 μm and an average particle size of 30-40 wt% of 1.0 -2.8μm range of two types of alumina. Add 15vol% of zirconia (containing 2 ~ 3mol% of yttrium oxide), add appropriate amount of dispersant, mix by ball milling, spray granulation, isostatic pressing, and fire in the temperature range of 1550 ~ 1620 C, it can be prepared for more than 2000 hours ceramic cylinder liner,and the forming and firing yield is high, and the raw material and process costs are low. The performance of zirconia-toughened alumina ceramics is better than 99 alumina ceramics, and the price is much lower than that of zirconia ceramics.Many occasions where alumina ceramics are incompetent show a better performance-price ratio than zirconia ceramics.
