钢铁在海水、海泥中锈层的穆斯堡尔谱的研究——Ⅱ.A_3钢与16Mn钢在海水、海泥中锈层的穆斯堡尔谱

STUDY ON RUST LAYER ON STEEL IN SEAWATER AND SEAMUD BY MOSSBAUER EFFECT Ⅱ . MOSSBAUER SPECTRA OF RUST LAYER ON A_3 AND 16 Mn STEEL IN SEAWATER AND SEAMUD

穆斯堡尔谱学对于研究钢的腐蚀产物是非常有用的（Simmons,1976;Vertes,1989）。Peev等人（1978）在实验中用穆斯堡尔谱学研究了α-Fe粉在海水中的腐蚀产物。马如璋等人（1981）对低合金钢在海水中的腐蚀锈层用穆斯堡尔谱学和X射线分析等方法进行过研究。但关于锈层的相组成目前尚有一些分歧,尤其是钢在海泥中锈层的相组成目前还很不清楚。本文将对A3钢和16Mn钢在海水、海泥区锈层相组成进行初步的分析研究。

Analysis of the phase composition of the rust layers of A3 and 16Mn steel in seawater and seamud by Mossbauer spectroscopy showed that in the same environment, the phase composition and amount are different.The amount of β-FeOOH of the outer rust layer on A3 and 16Mn steel in seawater-and seamud is less than that of the inner rust layer, but the amount of Fe3O4 of the outer layer is more than that of the inner layer. The amount of FeOOH on A3 steel in seawater is more than that in seamud. The amount of β-FeOOH on 16Mn steel in seawater is also more than that in seamud. The amount of α-FeO on 16Mn in seamud is more than that on A3 steel.
