ELECTROLESS NICKEL-BORON BATH
A method for depositing a metal coating containing nickel and boron on a substrate comprising preparing a plating bath having a pH of at least 10 comprising 0.175 to 2.10 moles per gallon of coating bath of nickel ions; 0.003 to 0.3 grams per gallon lead tnngstate as a stabilizer; a metal ion complexing agent in an amount effective to inhibit precipitation of the metal ions from the coating bath; an effective amount of a borohydride reducing agent; and optionally up to 1.05 moles per gallon of cobalt, immersing the substrate to be coated into the bath, electrolessly depositing the coating on the substrate, and heat treating at 375 to 750°F for one to 24 hours, whereby a metal coating is produced having a Knoop hardness, using a 100 g load, of at least 1,400.

CONICAL SPUI"rERING TARGET
U.S. Patent 6,066,242. May 23, 2000 D.A. Glocker, assignor to David A. Glocker, Rush, N.Y.
A magnetron for sputtering a target material onto a substrate to form a coating of the target material upon a surface of the substrate comprising a frusto-conical target off-spaced from the substrate and having an inner surface for being sputtered.
U.S. Patent 6,068,001. May 30, 2000 C. Pedrazzini and P. Giordani, assignors to Novamax ITB S.R.L., Milan, Italy
A pickling process for chromium containing stainless steel comprising placing the material to be treated in a bath kept at 30 to 70°C having the following composition: 20 to 100 g/L hydrochloric acid; 15 g/L ferric ion; 5 to 50 g/L hydrofluoric acid; and additives selected from the group consisting of emulsifiers, wetting agents, polishing agents, and acid attack inhibitors; wherein the total amount of the additives is about 1 g/L of pickling bath, keeping the bath under agitation by a continuous air flow or equivalent agitation means; maintaining pH lower than 2.5; and feeding an oxidizer quantity suitable for keeping the bath redox potential at values of at least 200 mV, said oxidizing agent being selected from hydrogen perox-

U.S. Patent 6,068,702. May 30, 2000 C Bertellotti et al., assignors to Nordson
Corp., Westlake, Ohio
A powder coating apparatus capable of converting between at least two different powder coating systems, the apparatus comprising an operating hood h a v i n g sides generally surrounding a powder coating area, with at least one side having an opening to allow the introduction of a part to be coated within the powder coating area; an air circulation system connected to the operating hood for drawing air from the powder coating area
as the part is coated with powder; and an adjustable air flow regulator operatively connected with the air circulation system for controlling the draw of air and powder out of the powder coating area between a first draw amount and a second, higher draw a m o u n t , w h e r e i n the first draw amount allows use of the hood as one powder coating systems and the second, higher draw amount allows use of the hood as another powder coating system. ELECTROSTATIC COATING SYSTEM
U.S. Patent 6,068,877. May 30, 2000 K. Seitz et al., assignors to Wagner International AG, Alstatten, Switzerland
A method of detecting and coating workpieces in an electrostatic coating system comprising applying a high voltage to an electrode of at least one electrostatic coating device, in which
a spray current containing electrical charges for charging particles of a coating material to be sprayed is generated by the electrode; passing an electrically conductive workpiece to be coated by the at least one coating device; determining the spray current of the high voltage electrode; detecting whether the workpiece is in front of the at least one coating device depending on the magnitude of the determined spray current; starting a discharge of the coating material by the at least one coating device when the spray current exceeds a first threshold value of spray current; and stopping the discharge of coating material by the at least one coating device when the spray current falls below a second threshold value of spray current.
