U Reiter et al., assignors to BASF

Coatings AG, Muenster-Hilltrup,

Germany

A process for the multilayer coat- ing of substrates with electrode- position and powder coating materials comprising applying at least one coat of an electrodeposi- tion coating material to a sub- strate; drying partially or wholly the at least one coat of the elec- trodeposition coating material at a temperature of less than or at

100°C; applying at least one coat of powder coating material to the at least one coat of an electrode- position coating material; and jointly baking.

ELECTROPLATING PROCESS l%S. Patent 6,254,755. July 3,200l

S. Mirua et al., assignors to

Mitsubishi Heavy Industries, Ltd.,

Tokyo

An electroplating process for plat- ing an Oldham ring having a ring body and a plurality of key por- tions extending outwardly from the ring body comprising soaking in a plating liquid; arranging at least two cathodes at respective positions on the ring body; and electroplating by passing electric current between the at least two cathodes and at least one anode contacting the plating liquid, wherein the respective positions are sufficiently angularly dis- placed from lines defined by opposing pairs of key portions to an extent such that the plurality of key portions are substantially uniformly plated.

PLATINUM COATING US. Patent 6,254,756. July 3,200l

A.F Maricocchi et al., assignors to

General Electric Co., Cincinnati

A method for preparing an article comprising providing an airfoil article precursor having a curved surface with a concavely curved first portion and a convexly curved second portion; position- ing a deposition anode in facing relationship to the concavely curved first portion of the curved surface, so that there is no anode in facing relationship to the con- vexly curved second portion of the

curved surface; and electrode- positing a platinum layer from solution onto the article precursor using the deposition anode, with deposition occurring primarily on the concavely curved first portion of the curved surface.

ANODIZING APPARATUS I.%S. Patent 6,254,759. July 3,200l

J Rasmussen, assignor to Pioneer

Metal Finishing, Green Bay, Wis.

A method of electrolytically treating a component comprising placing the component in an elec- trolyte solution; and applying a plurality of pulses to the solution and component, wherein the pulses have a pattern comprised of at least a first magnitude por- tion, a second magnitude portion, and a third magnitude portion, wherein the third magnitude is less than the first and second magnitudes, and wherein all three magnitudes are of the same polarity.

COATED ABRASIVE ARTICLE US. Patent 6,258,138. July lo,2001

R.d DeVoe et al., assignors to 3M

Innovative Properties Co., St. Paul,

Minn.

A method of preparing a coated abrasive article comprising pro- viding a backing; applying to the front surface of the backing an energy-curable, melt processable first binder precursor; exposing to an energy source to initiate at least partial curing; at least par- tially embedding a plurality of abrasive particles in the first binder precursor; and permitting sufficient cure to form a crosslinked coating with the abra- sive particles.
