In this study, corrosion weight loss experiments were conducted to explore the corrosion-inhibiting properties of a composite inhibitor consisting carboxymethyl chitosan (CMCS) and sodium humate (SH) at varying concentrations on EH40 steel in seawater. An investigation was into electrochemical behavior seawater mechanism through an test. X-ray photoelectron spectroscopy (XPS), scanning electron microscopy energy-dispersion (SEM-EDS), Fourier transform infrared absorption (FTIR), contact angle measurements performed confirm CMCS SH as well their inhibitors interface between steel. Furthermore, density functional theory (DFT) calculation supports experimental findings. The results show that CMCS, SH, are mixed type mainly inhibits cathodic reactions active site blocking mechanisms. Their inhibition effect increases with increase mass concentration, performs better scale than individual inhibitor. When concentration reaches 100 mg/L 50 mg/L, rate is 74.65%, potential shifts by about 47.39 mV,
