研究了1000～1300℃区间内的锆-4合金水蒸气腐蚀动力学。结果表明：在腐蚀反应初期，锆-4合金的水蒸气腐蚀动力学符合抛物线规律；随腐蚀反应的进一步进行，锆-4合金由于其表面形成大量微裂纹而出现加速腐蚀现象。
The kinetics of water vapor corrosion of zirconium-4 alloy in the range of 1000 ~ 1300 ℃ was studied. The results show that the corrosion kinetics of zirconium-4 alloy follows the parabolic law at the initial stage of corrosion reaction. With further corrosion reaction, zirconium-4 alloy accelerates corrosion due to the formation of a large number of micro-cracks on its surface.
