Abstract: The Cu-Sn-P-LiMn₂O₄ nanometer composite coating on the surfaces of Q₂₃₅ steel was prepared by the technology of electroless composite plating. The properties， compositions and morphology of the nanometer composite coating were studied by weighting， scanning electron microscope(SEM)， accelerated corrosion， room temperature oxida-tion， adhesiveness resistance tests， Auger Electron Spectroscopy(AES) and X-ray Photoelectron Spectroscopy(XPS). These investigations showed that the properties of the Cu-Sn-P-LiMn₂O₄ nanometer composite coating are superior to Cu-Sn-P alloy coating. The atomic number percentage compositions(%) of nanometer composite coating are Cu 80.00， P 4.50， O 6.00， Sn 1.50， C 3.50， Li 1.50， Mn 3.00， Cu-Sn-P-LiMn₂O₄ 96.50%.

Keywords: Cu-Sn-P-LiMn₂O₄ nanometer composite coating electroless composite plating corrosion resistance
