nonchromated oxide coating for aluminum
TRANSCRIPT
Nonchromated Oxide Coating for Aluminum U.S. Patent 5,487,949. Jan. 30, 1996 M.P Schriever, Kent, Wash.
A coated article exhibiting corrosion re- sistance and paint adhesion properties, comprising a substrate of aluminum or alu- minum alloy; and a cobalt conversion coat- ing formed on the substrate, comprising aluminum oxide A&O, as the largest vol- ume percent, and one or more cobalt oxides from the group consisting of COO, Co,O,, and Co,O,.
Abrasive Article U.S. Patent 5,489,235. Feb. 6, 1996 J.J. Gagliardi and RX. L&ken, assignors to 3M Co.. St. Paul, Minn.
An abrasive article comprising a surface having a machine direction axis and oppo- site side edges, each side edge being par- allel to the machine direction axis, and a plurality of parallel rows of precisely shaped abrasive composites in fixed posi- tion on the surface.
Etching Monitor U.S. Patent 5,489,361. Feb. 6, 1996 S.G. Barbee et al., assignors to IBM Corp., Armonk, N. Y
A method for contactless, real-time, in- situ monitoring of a chemical etching pro- cess.
Target for Reactive Sputtering U.S. Patent 5,489,367. Feb. 6, 1996 K. Kubota and A. Hiraki, assignors to Hitachi Metals Lfd., Tokyo
A method for forming a substantially stoichiometric titanium nitride film, which comprises the step of sputtering a target comprising titanium and nitrogen in the presence of a sputtering gas containing ni- trogen, wherein the target has a nitrogen/ titanium atomic ratio of 0.20 to 0.90.
Aqueous Zinc Solution U.S. Patent 5,489,373. Feb. 6, 1996 A. Parlhasarafhi, assignor to Olin Corp., New Haven, Conn.
A method for preparing an electrolyte for the deposition of a zinc containing an- titamish coating on a metallic substrate by inhibiting the precipitation of zinc from the electrolyte comprising supplying an aque- ous medium having a pH in excess of 7; dissolving in the aqueous medium silicon, from a water-soluble silicon source, in an amount that provides a silicon ion content effective to inhibit precipitation of zinc frmo the electrolyte; and subsequently dis- solving 0.8 to 30 g/L of zinc ions.

Removing heavy metals from rinse water. Achieving EPA, State and Municipal compliance limit always. Giving final concentrations of 0.3 PPM, 0.05 PPM, 0.001 PPM. Treating water that is recycled and producing “zero” liquid discharge. Recovering heavy metals as 20% - 45% heavy metal sludge or as scrap metal. Providing low, lower, lowest total treatment cost at no capital investment if desired. In combination with multiple-tank counter-current low-retur pre-rinsing, saving 99% of otherwise-lost plating metal.
