某核电厂发电机氢气冷却器气软管破损原因分析

摘要

The tresis of hydrogen air hosepipe on the refrigerator was found in a nuclear power plant maintenance process. With the analysis of chemical component, material property, microstructure of tresis and working condition, it is concluded that the tresis was casued by the fretting corrosion of stainless steel net.%某核电厂日常检查时发现发电机氢气冷却器的其中一段连接软管存在穿孔缺陷。通过分析该段软管的化学成分，材料性能，穿孔的微观形貌等，并结合软管周围的工作环境，得出软管的穿孔是由不锈钢网罩的摩擦腐蚀所致。
