摘要
研究了低合金钢-硝酸盐溶液体系的应力腐蚀行为。测定了温度,浓度和电极电位对各种腐蚀类型及腐蚀强度的影响。建立了相应的温度-浓度-电位SCC图。确定了该体系的下临界电位和SCC敏感电位范围。讨论了采用阴极保护的可能性。
The stress corrosion cracking (SCC) behaviour of low alloy steel in nitrate aqueous solution was investigated. The effect of temperature, medium concentration and potential on various corrosion types and thier intensities was determined. The temperature-concentration-potential SCC diagram was established. The down critical potential and sensibility zone of SCC was ascertained. The applicability of cathcdic protection was discussed.
