摘要：
The hydrothermal corrosion and strength degradation of aluminum nitride (AIN) ceramics were investigated. The weight gain in AIN ceramics after corrosion occurred because of the formation of boehmite. The reaction kinetics of AIN with mater were diffusion controlled through the boehmite product layer. At 180 degreesC, immersion in mater caused no strength degradation, and water vapor caused a 20 % strength degradation. At 300 degreesC, immersion in water caused a 20 % strength degradation, and water vapor caused a 30 % strength degradation.
