Processes for providing laminated coatings on workpieces, and articles made therefrom
Methods for providing laminated coatings on metal articles using electroplating methods such as barrel plating, vibratory plating, rocker plating or other non-rack methods that involve movement of articles to be plated in a containment apparatus, as well as articles made from such processes. Embodiments of such processes involve mass-transfer modulation to provide compositionally modulated coatings.
Method and apparatus for manufacturing electroplated steel sheet
A method for manufacturing an electroplated steel sheet by continuously performing electroplating on a steel sheet, the method including disposing a slit gas nozzle having an ejection port having a width wider than a width of the steel sheet in a width direction of the steel sheet on a side of an exit of an electroplating cell for the steel sheet to pass through, and ejecting a gas through the slit gas nozzle toward the steel sheet.
LEAD MEMBER

Coating for functional parts made of metal
The invention relates to a coating of metal surfaces of functional parts made of metal, preferably baking plates and a method for producing such a coating, wherein at least one coating (2) comprising an alloy is applied galvanically to the metal surface (6), wherein the coating comprises a surface layer (3) which consists of a galvanically applied alloy which contains nickel (Ni), phosphorus (P) and tin (Sn) as the main component, and wherein the surface layer (3) is an alloy layer obtained by pulsed deposition, preferably inverse pulsed deposition from a galvanic bath.
Method for preparing optical articles with multi-layer antireflective coatings
The present invention is directed to a method for preparing a coated optical article including providing a non-conductive substrate; forming a conductive coating layer over the substrate; electrodepositing a first electrodepositable coating composition over the conductive coating layer to form a first electrodeposited inorganic coating layer; and electrodepositing a second electrodepositable coating composition over the first electrodeposited coating layer to form a second electrodeposited inorganic coating layer thereover, thereby forming a multi-layer antireflective inorganic coating over the conductive coating layer. Each of the first electrodepositable coating composition and the second electrodepositable coating composition is different one from the other, and each includes a sol prepared from a composition of a metal oxide precursor and protic acid such that each coating composition is hydrolyzed. Coated optical articles are also provided.

Iron tungsten coating formulations and processes
An electrolyte solution for iron-tungsten plating is prepared by dissolving in an aqueous medium a divalent iron salt (e.g., iron (II) sulfate) and an alkali metal citrate (e.g., sodium citrate, potassium citrate, or other alkali metal citrate) to form a first solution, dissolving in the first solution a tungstate salt (e.g., sodium tungstate, potassium tungstate, or other potassium tungstate) to form a second solution, and dissolving in the second solution a citric acid to form the electrolyte solution. An iron-tungsten coating is formed on a substrate using the electrolyte solution by passing a current between a cathode and an anode through the electrolyte solution to deposit iron and tungsten on the substrate.
