TI - Electrochemical and Microstructural Analysis of FeS Films from acid Chemical Bath at different temperature, pH, TI - Electrochemical and Microstructural Analysis of FeS Films from acid Chemical Bath at different temperature, pH,通过在酸性化学镀液中沉积合成的硫化铁薄膜,研究了4130合金钢的耐蚀性和腐蚀产物。测试在不同的温度(25°C - 75°C)、pH值(2-4)和浸泡时间(24-72小时)下进行。采用线性极化电阻法(LPR)监测腐蚀行为。采用x射线衍射(XRD)、能量色散x射线(EDX)和扫描电镜(SEM)对腐蚀产物进行了表征。结果表明,在试验条件下,随着合金表面硫化铁保护膜的形成,温度的升高、浸泡时间的延长和pH的降低都直接提高了钢的腐蚀速率。随着温度的升高,腐蚀速率开始上升,但随着硫化铁晶体结构的转变,腐蚀速率大幅下降。SN - 1687-9325 UR - https://doi.org/10.1155/2016/1025261 DO - 10.1155/2016/1025261 JF - International Journal of Corrosion PB - Hindawi Publishing Corporation KW - ER -
