The effect of copper content, on the nature and roughness of the corrosion products formed on carbon steel in a synthetic brine saturated with CO₂ at room temperature, was studied using a jet impact chamber tuned at different impact angles. Corrosion rate was determined by linear polarization resistance, and steels behavior was described by electrochemical impedance spectroscopy. The corrosion products formed on steel were characterized by scanning electron microscopy, electron-dispersive analysis, optical profilometry and grazing incidence X-ray diffraction. The chemical composition and morphology of corrosion products affected corrosion rate. For the different steels, Fe₃C and iron oxides provided a low degree of protection. Steels with higher copper contents showed a decrease in corrosion rate due to the formation of copper oxides (CuO and Cu₂O), which apparently offered a stronger physical barrier between the aggressive environment and the substrate. Small roughness of corrosion products was correlated with more compact and uniform layers of corrosion products and also to lower corrosion rates.

使用在不同冲击角下调整的射流冲击室，研究了铜含量对室温下用CO ₂饱和的合成盐水中碳钢上形成的腐蚀产物的性质和粗糙度的影响。腐蚀速率由线性极化电阻确定，钢的行为由电化学阻抗谱描述。通过扫描电子显微镜，电子弥散分析，光学轮廓分析和掠入射X射线衍射对钢上形成的腐蚀产物进行了表征。腐蚀产物的化学组成和形态会影响腐蚀速率。对于不同的钢，Fe ₃C和铁氧化物提供的保护程度较低。铜含量较高的钢由于形成了铜氧化物（CuO和Cu ₂ O）而导致腐蚀速率降低，这显然在侵蚀性环境和基材之间提供了更强的物理屏障。腐蚀产物的低粗糙度与腐蚀产物的更致密和均匀的层以及较低的腐蚀速率有关。
