In this paper, the corrosion rate of copper is the seawater that has been studied after laser surface treatment with local energy 1 Joul to get to the surface melting. The application of laser surface treatment to improve the corrosion resistance of copper using electrochemical polarization. The surface morphology and structure properties have been studied using optical microscope (OM), Atomic force microscopy (AFM) and XRD, XRF. Besides macro-hardness. The results show that higher corrosion resistance, higher hardness and lower average roughness due to laser surface treatment.
