Abstract: An anticorrosion treatment method for a copper-containing material comprises: carrying out a sealed and pressurized reaction on a copper-containing material and a stabilizer in presence of a polar solvent and any assistant, the stabilizer being a compound capable of providing formates, so that the formates are adsorbed on the surface of the copper-containing material. In the method, formates are modified on the surface of the copper-containing material, accordingly, the oxidation resistance capability and the stability of the copper-containing material can be significantly improved while the electrical conductivity of the copper-containing material is not reduced, and the corrosion resistance of the copper-containing material and especially, the salt and alkali corrosion resistance of the copper-containing material are significantly improved.
