Low carbon steel pipeline material is usually to transport wet gas. The presence of water in gas may lead corrosion and leakage. To enhance corrosion resistance of this material, we investigated electrodeposited of Sn-Zn on various composition Zn. Microstructure, structure, thermal properties and corrosion behaviour were analysed with Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC) and Potentiodynamic Polarization. Electrodeposited Sn-Zn with smallest Zn content shows highest corrosion rate. With various composition, XRD pattern shows tetragonal crystal structure. The various Zn content have changed the melting point and the enthalpy. Electrodeposited Sn-Zn on low carbon steel pipeline material enhance the corrosion resistance.
