    摘要： A method of producing a composite electroless nickel layer on a substrate is described. The method includes the steps of contacting the substrate with a composite electroless nickel plating bath and generating an electrostatic field in the electroless nickel plating bath. The electric field is generated by placing an anode in the electroless nickel plating bath and connecting the anode to a positive terminal of a DC rectifier, and connecting the substrate to a negative temiinal of the DC rectifier, and preferably inserting a capacitor into the circuit to prevent passage of current. An attractive force generated by the electrostatic field increases the attraction of the positively charged PTFE particles to the negatively charged substrate and drives the positively charged PTFE particles to the negatively charged substrate.

    摘要： An electrolytic cell and a method of electrochemical oxidation of manganese(II) ions to manganese(III) ions in the electrolytic cell are described. The electrolytic cell comprises (1) an electrolyte solution of manganese(II) ions in a solution of at least one acid; (2) a cathode immersed in the electrolyte solution; and (3) an anode immersed in the electrolyte solution and spaced apart from the cathode. Various anode materials are described including vitreous carbon, reticulated vitreous carbon, woven carbon fibers, lead and lead alloy. Once the electrolyte is oxidized to form a metastable complex of manganese(III) ions, a platable plastic may be contacted with the metastable complex to etch the platable plastic. In addition, a pretreatment step may also be performed on the platable plastic prior to contacting the platable plastic with the metastable complex to condition the plastic surface.

    摘要： A method of adjusting and controlling the color of trivalent chromium deposits is provided. The method includes the steps of: (a) measuring the color of a trivalent chromium deposit standard; (b) adding one or more color enhancing additives to a trivalent chromium electrolyte; (c) contacting the substrate with the trivalent chromium electrolyte containing the one or more color enhancing additives to deposit trivalent chromium on the substrate; (d) measuring the color of the color-enhanced trivalent chromium deposit; (e) comparing the color of the color-enhanced chromium deposit to that of the standard; and (f) if necessary, adjusting the amount of the one or more color enhancing additives added to the trivalent chromium electrolyte if the color of the color-enhanced chromium deposit is outside of a desired optical variation from that of the standard color-enhanced chromium deposit. The color of the trivalent chromium deposit may be measured using a spectrophotometer.
