Abstract:This paper introduces an innovative new technology and technology for mould remanufacturing, that is, electrochemical copper reinforcement and remanufacturing technology, which is based on normal temperature and pressure in aqueous solution composed of copper salts, hard nanoparticles, etc. Under the action of electric field, copper ions deposit in cathode while embedding hard nanoparticles into copper metal to form copper-based nanocomposites.
