Abstract

1312723 Plating by fusion electrolysis NIPPON KOKAN KK 13 Aug 1970 [26 Aug 1969] 39011/70 Heading C7B An article e.g. a fastener having a surface of readily oxidisable metal or alloy, e.g. Al, Ti, Cr, alloy thereof or stainless or Cr steel, is electroplated e.g. with Al in a molten salt bath after pickling the article in a mixture of nitric or boric acid and HF to dissolve oxide film, then washing with an anhydrous organic solvent, or with water followed by drying in a vaccuum. After washing with the organic solvent, the article may be dried by blasting a stream of hot inert gas e.g. N 2 or A prior to plating in the molten salt bath, e.g. of AlCl 3 and NaCl with or without KCl using Al anode plates. A.C. may be passed between two Al plates or rods placed either side of the article to clear its surface prior to plating. The solvent may be a ketone e.g. acetone, an alcohol e.g. methanol, ethanol, glycerine, ethyl ether, a carboxylic acid e.g. acetic acid anhydride. Prior to pickling, the article may be degreased with potassium silicate solution, or petroleum benzene and acetone. The plated article may be washed and rinsed under ultrasonic wave vibrations to remove molten salt. After drying, the plated article may be peened using glass beads. Specified alloys plated include: Ti-6% Al-4% V, Ti-8% Al -1% Mo-1% V, Al-12% Si and Al-8À5% Si-3À5% Cu.
