摘要
穆斯鲍尔谱(MS)分析是研究物质结构的一种近代新技术.本文对运行一段时间后的核潜艇动力装置某些部件的大气腐蚀产物作了MS谱研究.得到了×××艇主蒸汽管道及调压阀两个锈蚀产物的穆斯鲍尔谱.经解谱分析,可以认证该两个锈蚀产物的主要成分是α-Fe_2O_3,γ-Fe_2O_3及β/γ^-FeOOH本文表明MS谱技术也是研究×××艇锈蚀的一种有效方法.本文对该艇有关部件的锈蚀机理也作了初步讨论.
Mossbauer Spectroscopy (MS) analysis is a modern and new technique to study material structure.a MS study of the atmospheric corrosion products of nuclear submarine power plant which has run for a long period of time is given.The MS of two corrosion samples of the steam main and the adjustable pressure valve in submarine No.××× are obtained.We find out that the both are composed of α-Fe_2O_3, γ-Fe_2O_3 and β/γ-Fe OOH.It is proved that the MS technique is an effective method to study the problem of the submarine plant corrosion too.The formation mechanism of the corrosion products of the submarine No.××× is also discussed primarily.
