| 摘 要： | 采用特制高压釜设备,研究304L不锈钢、316L不锈钢、317L不锈钢和镍基合金(Incoloy 800)在高温高压醋酸溶液中的腐蚀,初步探讨了不锈钢和镍基合金在醋酸溶液中的腐蚀机理及Ni和Mo元素对提高不锈钢耐蚀性能的影响.结果表明,温度对不锈钢和镍基合金耐蚀性有显著影响,随着温度的升高,腐蚀速率逐渐增大,当温度升高到一定值,不锈钢的耐蚀性会急剧下降.在低温醋酸溶液中,Ni对于提高不锈钢耐蚀性是有益的;在高温醋酸溶液中,Ni对于提高不锈钢耐蚀性没有显著影响.在低温醋酸溶液中,Mo对于提高不锈钢耐蚀性没有显著影响;在高温醋酸溶液中,Mo对于提高不锈钢耐蚀性是有益的.

| Abstract: | A special autoclave was used to study corrosion behavior of 304L,316L,317L stainless steel and nickel based alloy(Incoloy800) in acetic acid solution.The results showed that temperature plays a critical role in corrosion resistance of stainless steel and nickel based alloy,their corrosion rates was increased with the increasing of temperature,and the corrosion resistance of stainless turned worse suddenly when the temperature increased to some value.Ni and Mo had different influence on corrosion resistance at various temperature.For increase in corrosion resistance of stainless,Ni is effective in acetic acid at low temperature,and Mo is effective in acetic acid at high temperature. |
