【摘要】:研究了一種綠色緩蝕劑酒石酸鈉在微堿性水溶液中對碳鋼的緩蝕效果,并分析了經(jīng)酒石酸鈉處理后碳鋼表面上緩蝕膜的基本組成。電化學測試結果表明,酒石酸鈉的緩蝕性能優(yōu)于葡萄糖酸鈉,可在碳鋼表面形成致密的氧化物膜。X射線光電子能譜(XPS)顯示,緩蝕膜的主要成分為α-Fe_2O_3和FeOOH,并含有少量螯合的酒石酸鈉和非均勻分布的CaCO_3沉積物。傅里葉變換紅外光譜(FTIR)分析和掃描電子顯微鏡(SEM)觀察同樣印證了上述結論。
[Abstract]:The inhibition effect of sodium tartrate, a green corrosion inhibitor, on carbon steel in slightly alkaline aqueous solution was studied, and the basic composition of corrosion inhibition film on carbon steel surface treated with sodium tartrate was analyzed. The electrochemical results show that sodium tartrate is superior to sodium gluconate in corrosion inhibition, and can form a dense oxide film on the surface of carbon steel, which can be shown by X-ray photoelectron spectroscopy (XPS). The main components of the film are 偽 -Fe _ 2O _ 3 and FeOOH, and contain a small amount of chelate sodium tartrate and heterogeneous CaCO_3 deposits. Fourier transform infrared spectroscopy (FTIR) analysis and scanning electron microscopy (SEM) observations also confirm the above conclusion.
