6) sulphide corrosion
硫化腐蚀
1.
The results showed that the tubes had suffered the high temperature oxidative and sulphide corrosion for the operation temperature being higher than the suitable, though reheating tubes were made by Cr5Mo steel which has good anticorrosion and mechanism performance.
应用扫描电子显微镜、能谱分析以及X射线衍射仪对焦化加热炉炉管的高温腐蚀形貌,腐蚀物成分以及物相进行了分析,结果表明,尽管加热炉管用材是抗腐蚀性能和高温机械性能均良好的Cr5Mo钢,但由于炉膛操作温度过高,且燃料中含硫,炉管不但发生高温氧化腐蚀,还发生硫化腐蚀,使破坏加速,最终导致炉管失效。
补充资料:氢蚀
hydrogenattack:氢蚀也是氢脆的一种表现形式。它出现在石油高压加氢和液化石油气的设备中。其作用机理是在300~500℃范围内,由于高压氢与钢内的碳发生化学反应在晶界上产生高压甲烷(CH4)而使材料脆化。
