    • The invention features and methods and compositions for oxide production on a Copper substrate, e.g., a Copper or Copper alloy substrate, to provide for improved adhesion of Copper substrate to polymeric material, e.g., such as used in manufacture of printed circuit boards. The oxide-producing compositions of the invention, which may be either acidic or ammoniacal, comprise 1) a source of Cu++ (Cupric) ions; 2) a source of a primary electrolyte that is non-interactive with Copper ions; 3) a Cuprous ligand, e.g., a halide ion, preferably chloride, which also serves as a secondary electrolyte; and 4) an optional organic. Acidic oxide-producing compositions comprise a strong acid as the primary electrolyte. The primary electrolyte of ammoniacal oxide-producing compositions is a non-interactive, ammonium salt of acid, which provides a highly soluble Cupric ammonium salt. The secondary electrolyte of the oxide-producing compositions is selected so as to be compatible with the primary electrolyte.

    • From the time that they are immersed into a marine environment, bronze propellers are prone to attack by marine organisms, such as barnacles, coral and algae, which attach themselves to the bronze metallic surface, creating lumps on the propeller, which adversely affect its balance and cause impedance and vibration of the propeller and its boat in the water. Ant-fouling paints are either too toxic for the marine environment of lack smoothness on the surface. These problems have been overcome by a combination of known steps, namely, polishing the propeller to prepare it for electroplating, cleansing to remove all traces of dirt and grease, electroplating with copper to a depth of at least 0.005null or 0.15 mm, followed by spraying with a standard solution (5%) of sodium hypochlorite and sodium chloride in a suitable container to form a firmly adhering conversion coating of basic cupric chloride and then sealing for at least twenty-four hours. The preferred procedure for polishing is 60null grit size at 3500 sfm for roughing, followed by 180null grit size at 5500 sfm for finishing using grease as a polishing aid. Electroplating with copper to the minimum depth provides a smoothing effect ranging from 70 to 90 per cent. The container in which the hypochlorite spraying is carried out is preferably kept sealed until just before fitting and launching. A life expectancy of five (5) years can be anticipated with minimal maintenance every time the vessel is slipped.
    • 从浸入海洋环境的时候，青铜螺旋桨容易受海洋生物侵袭，例如藤壶，珊瑚和藻类，它们附着在青铜金属表面，在螺旋桨上产生不利影响其平衡的块状物 并引起螺旋桨及其船在水中的阻抗和振动。 防污涂料对于表面缺乏平滑度的海洋环境来说太毒了。 这些问题已经通过已知步骤的组合来克服，即抛光螺旋桨以准备其用于电镀，清洁以除去所有痕迹的污垢和油脂，用铜电镀至至少0.005“或0.15mm的深度，随后 通过在合适的容器中喷洒次氯酸钠和氯化钠的标准溶液（5％）以形成基本氯化铜的牢固粘附的转化涂层，然后密封至少24小时。 抛光的优选步骤是3500＃s的毛坯尺寸为60＃，用于粗加工，其次是180＃砂砾尺寸，5500 sfm，用于润滑脂作抛光助剂。 用最小深度的铜电镀提供70％至90％的平滑效果。 进行次氯酸盐喷雾的容器优选保持密封直到安装和发射之前。 预计在五（5）年的预期寿命，每次船只滑倒时，维护量最少。
