NONCHROMATED OXIDE COATING
US. Patent 6,432,225. Aug. 13,2002 M.Z? Schriever, assignor to The Boeing Co., Seattle, Wash. An improved process that is com- mercially practical for forming an oxide film cobalt conversion coat- ing exhibiting corrosion resist- ance and paint adhesion proper- ties on a substrate, where the substrate is aluminum or alu- minum alloy.
ELECTROPLATING A DUAL-SIDE
US. Patent 6,432,291. Aug. 13,2002 I? Vivares, et al., assignors to Advanced Micro Devices, Inc., Sunnyvale, Calif A method of electroplating a dual- sided workpiece, which comprises providing an electrically insula- tive substrate including first and
second of opposed major surfaces, with respective first and second pluralities of electrically conduc- tive features formed on the major surfaces; providing an electrical contractor in simultaneous touch- ing electrical contract with each feature of one the pluralities of electrically conductive features; and contacting with at least one electroplating bath while apply- ing an electrical potential and simultaneously electroplating at least one layer on the pluralities of electrically conductive features.

force to cause a bed of electrically conductive particles to flow across a particles contacting surface of a cathode support spaced from an anode, where the force has a direction and the particle contact- ing surface is at an angle between 15 and 85” relative to the direc- tion of the force; avoiding sus- tained contact between the parti- cles and the anode without use separator; and providing an elec- trical current between the bed of particles and the anode, thereby electrodepositing metal on the electrically conductive particles as they flow across the particle contacting surface of the cathode.
