LOW-ETCH ALKALINE COMPOSITION
ZINCATE
U.S. Patent 6,080,447. June 27, 2000 K.L. Ferroni et al., assignors to Enthone-OMI Inc., West Haven, Conn.
A method for metal plating aluminum to provide a metal coating having thermal retention of paramagnetic properties when metal plated with a paramagnetic metal coating comprising contacting a cleaned and etched aluminum substrate for an effective time with an aqueous zincating composition to form a zincate coating on the aluminum substrate, the zincate composition comprising, in g/L NaOH in an amount of about 50 to saturation; ZnO in an amount of about 5 to 50; Fe3+ in an amount of about 0.15 to 0.5; a chelator in an amount effective to chelate the Fe3+ and NaNO, in an amount of 0.01 to 10, and metal plating the zincated aluminum substrate. CHIP-RESISTANT PAINT FILM
COMPOSITE
U.S. Patent 6,083,563. July 4, 2000 E. Yamanaka et al., Japan
A method of forming a chipresistant composite paint film, which comprises applying serially on an electrodeposition coat baked onto a substrate, an antichip primer and an intermediate coating in the wet-on-wet method and baking the two wet coats in one step, wherein the antichip primer comprises an aqueous dispersion of an ethylene copolymer, a water-based urethane resin, and a water-miscible organic solvent; and the intermediate coat72

the hollow section, and for collecting the jetted composite plating liquid from a region surrounding the cylindrical electrode.
U.S. Patent 6,083,627.
An article of manufacture comprising a substrate selected from the group consisting of metal, glass, and ceramic coated on at least one surface thereof with coating formed from a resin composition consisting essentially of from 0.01 to 45% by weight polyvinylidene fluoride based polymer; and from greater than 55 to 99.99% polyamide polymer selected from the group consisting of polyamide 11 and polyamide 12. COMPOSITE
PLATING APPARATUS
U.S. Patent 6,086,731. July 11, 2000 0. Ishigami et al., assignors to Honda Giken Kogyo KK, Tokyo
An apparatus for forming a composite plating film on an inner surface of a hollow section of a workpiece, which comprises a cylindrical electrode adapted to be disposed in the hollow section of the workpiece with a surrounding gap left between a surface of an outer wall of the electrode and the inner surface of the hollow section; and a plating liquid circulating mechanism for supplying composite plating liquid, consisting of ceramic particles mixed in plating liquid, to an interior of the cylindrical electrode, for passing the composite plating liquid through the through-holes of the outer wall of the electrode to be then jetted onto the inner surface of
ELECTROPLATING BATH FOR SLIDING BEARINGS
U.S. Patent 6,086,742. July 11, 2000 H. U. Huhn et al., assignors to GlycoMetall-Werke, Glyco B.V. & Co. KG, Weisbaden
A process for producing multilayer materials for plain bearings comprising preparing a metallic backing layer; applying a bronze layer to the backing layer; electrodepositing a binary layer on the bronze layer selected from a group of materials consisting essentially of lead-based and tinbased alloys in an electroplating bath having a nonionic wetting agent and a benzene derivative anodically activating at least one surface layer of the binary layer; and electroplating a molybdenum-based running-in layer on the binary layer. ELECTROLESS GOLD DEPOSITION
U.S. Patent 6,086,946. July 11, 2000 G.L. Ballard et al., assignors to International Business Machines Corp., Armonk, N.Y.
