摘要:
首次研究了“华光礁Ⅰ号”出水铁器腐蚀产物及有害盐脱除,其中HTQ6#铁器锈蚀产物表面电阻率为(3×103)~(1×108)Ω,已完全矿化且具有磁性,腐蚀产物主要为Fe3O4、α-FeOOH、γ-FeOOH、FeOCl。为避免有害锈γ-FeOOH、 Abstract: Corrosion products on iron ware from “Huaguang Reef Ⅰ” and the removal of harmful salts were investigated.The surface resistivity of the rust on one iron ware named HTQ6# was (3×103)—(1×108) Ω, and the rust was completely mineralized.The rust including Fe3O4, α-FeOOH, γ-FeOOH and FeOCl was magnetic.In order to avoid the damage of the harmful rust including γ-FeOOH and FeOCl on the original appearance of the cultural relics, desalination process using constant current density of -0.5 mA·cm-2 in 2.5% NaOH solution was studied.The results were shown as follows.The proportion of chloride ion removed was 53.31%, which was higher than that by using impulsive current, at the final time of desalination for 264 h.Meanwhile, the concentration of chloride ion in the solution was 6.1 mg·L-1 and electrical efficiency was 1.95%.In this process, the amount of chloride ion in the iron matrix decreased from 2.03% to 0.95% at applied potential of -2.25—-1.61 V with the potential stabilized at -1.61 V. 引用本文 杨传森1,王菊琳1,张治国2. 华光礁出水铁器腐蚀产物及脱盐研究 [J].
