求翻译:An AISI 420 (13Cr) martensitic stainless steel was tested in environments containing different amounts of H2S, CO2, Cl− and acidity, at temperatures varying from 22 to 140°C. The sulphide stress corrosion cracking (SSCC) resistance was assessed with three different types of testing methods: uniaxially constant load; co是什么意思? 待解决

一个AISI 420(13Cr)马氏体不锈钢在含有不同数量的硫化氢,二氧化碳,氯离子和酸度,温度不同从22到140 ° C。的环境测试评估三种不同类型的测试方法:单向恒定负载;恒应变(U型)和慢应变速率(SSRT)的硫化物应力腐蚀开裂(SSCC)的阻力。高到SSCC的敏感性,这证明在硫化氢环境中,而二氧化碳的增加有抑制作用,由于保护膜的形成。高氯离子浓度和低pH值有不利影响。此外,SSCC的易感性与实际腐蚀速率:高腐蚀速率造成更多的离域的攻击。在这方面,氯,硫化氢和酸化pH值可能会增加腐蚀速率上SSCC的行为与最后的有益作用。 SSRT技术,由于其灵敏度高,表明应力腐蚀开裂的CO2饱和的硫化氢
