激光表面处理对Zr－4合金板材疖状腐蚀的影响

The Effect of Laser Surface Treatment on the Nodular corrosion of Zircaloy-4

摘要:

研究了几种激光表面处理工艺对不同状态的Ｚｒ－４合金板材泡疖腐蚀的影响。实验结果表明：激光表面处理可以显著提高Ｚｒ－４合金抗疖状腐蚀性能；激光表面处理前Ｚｒ－４合金板材的状态（消除应力退火态、再结晶退火态、冷加工态）对激光表面处理后板材的疖状腐蚀性能的影响不明显

Abstract:

The effect of the laser surface treatment by different process paramaters on the nodular corrosion of zircaloy-4 plates in different states has been investigated. The results show that the nodular corrosion resistance of zircaloy-4 can be improved remarkably by laser surface treatment. The metallurgical states (stress relieved, recrystallized and cold-worked) before laser treatment for zircaloy-4 has little effect on the nodular corrosion resistance.
