内容提示: TRIVALENT CHROMATE CONVERSIONCOATINGBACKGROUND OFTHE INVENTION[0001] The present invention pertains to the art of metalsurface treatment, and more particularly, to conversion coat-ings for plated metals.[0002] The invention is particularly suited to treatment orpassivation of zinc-plated ...
as a decorative finish, or to maintain electrical conductance. the process takes its name from the chromate present in chromic acid, also known as hexavalent chromium, the most commonly used chemical in the immersion bath phase by which the coating is applied. q2 is cro 4 an acid or base?
X-ray photoelectron spectroscopy measurements indicated that the conversion coating had a surface of CrOOH and Cr(VI), enriched in ferricyanide. The bulk of the coating was an equal mixture of CrOOH and Cr2O3 with significant levels of F and Fe, the latter implying the presence of ...

Circle 455 on the reader service card BLACK CHROMATE Taskem Inc., Brooklyn Heights, Ohio Tasdip Matrix Black Chromate is an advancement in nonsilver chromate technology designed to produce a glossy black chromate conversion coating on zinc/iron electrodeposits that contain a minimum of 0.5% by ...
A conversion coating that tends to give off a greenish colour doesn't have the silver particles spaced uniformly. The study doesn't exactly say what causes this, yet states that certain impurities that remain on the surface may cause corrosion or disruption of the silver particle spacing thus ...
