Using a plasma-assisted chemical vapor deposition (PACVD) process, carbon steel samples were coated with an organosilicon layer less than 2.5 microns thick. Ellipsometry, Fourier transform infrared (FTIR) spectroscopy, contact angle, scanning electron microscopy (SEM), and atomic force microscopy (AFM) were used to analyze the films. Additionally, gravimetric experiments were used to determine the electrochemical properties of the organosilicon coatings. Organosilicon-coated carbon steel specimens demonstrated significantly enhanced resistance to corrosive conditions, such as 3% aqueous sodium chloride solutions. The surface preparation method has a considerable influence on the morphological and electrochemical properties of the steel. Argon pretreatment significantly enhances the corrosion resistance of organosilicon-coated steel. Gravimetric research demonstrated that pretreatment with argon plasma resulted in less weight loss and corrosion than pretreatment with nitrogen plasma. The link between quantum computing and experimental data using density functional theory (DFT) and molecular dynamics (MD) was used.
采用等离子体辅助化学气相沉积（PACVD）工艺，在碳钢样品上涂覆了厚度小于2.5微米的有机硅层。使用椭偏仪、傅里叶变换红外（FTIR）光谱、接触角、扫描电子显微镜（SEM）和原子力显微镜（AFM）对薄膜进行分析。此外，采用重量法实验来测定有机硅涂层的电化学性能。涂覆有机硅的碳钢试样在诸如3%氯化钠水溶液等腐蚀条件下表现出显著增强的耐腐蚀性。表面处理方法对钢的形态和电化学性能有相当大的影响。氩气预处理显著提高了有机硅涂层钢的耐腐蚀性。重量法研究表明，与氮等离子体预处理相比，氩等离子体预处理导致的重量损失和腐蚀更少。利用密度泛函理论（DFT）和分子动力学（MD）建立了量子计算与实验数据之间的联系。
