Application number 201610085510. 2 (12) Invention patent application (10) Application publication number CN 105543912 A (43) Application publication date 2016.05.04 Application date 2016. 02. 15 Applicant Shanghai Institute of Applied Technology Address: No. 120-121, Caobao Road, Xuhui District, Shanghai 200235 Inventor Lin Hualin, Funing, Feng Chenqi, Jiang Jibo, Han Sheng Patent agency Shanghai Jingsheng Intellectual Property Agency Co., Ltd. 31253 Agent Yang Jun Name of invention A method for preparing compound surfactant/La-Ni-Mo-W co-deposition coating on copper substrate Summary The present invention discloses a method for preparing a compound surfactant/La-Ni-Mo-W co-deposition coating on a copper substrate. By polishing, degreasing, and etching the pure copper sheet; then use the copper sheet as the cathode and the platinum-plated titanium mesh plate as the anode; electroplating under the condition of a constant temperature water bath can obtain the compound surfactant/La- Ni-Mo-W co-deposited coating. The present invention adopts a method of adding a compound surfactant and rare earth element lanthanum (La) to a nickel (Ni)_molybdenum (Mo)_tungsten (W) plating solution to prepare a co-deposition coating, and the resulting compound surfactant/La -Ni-Mo-W codeposition coating has the advantages of uniform thickness, high hardness, good wear and corrosion resistance, good stability and high hydrogen evolution activity. |
