摘要:
A method of disposing a corrosion resistant system to a substrate may comprise applying a plating material to the substrate; forming a chemical conversion coating solution by combining a solvent, at least one corrosion inhibitive cation comprising at least one of zinc, calcium, strontium, magnesium, or aluminum, at least one corrosion inhibitive anion comprising at least one of phosphate, molybdate, or silicate, and a complexing agent; and applying the chemical conversion coating solution to the plating material on the substrate.
摘要:
When depositing a metal or a compound of the metal from a liquid crystal phase comprising a metal compound, e.g. a metal salt, by electrochemical means, high concentrations of the salt may be employed by using an ionic surfactant in place of the commonly used non-ionic surfactant.
摘要:
An article is coated with a multilayer coating comprising a nickel layer deposited on the surface of the article, a nickel-tungsten-boron alloy layer deposited on the nickel layer, a chrome layer deposited on the nickel-tungsten-boron alloy layer, a refractory metal, preferably zirconium, strike layer deposited on the chrome layer, and a refractory metal compound, preferably zirconium nitride, deposited on the refractory metal strike layer. The coating provides the color of polished brass to the article and also provides abrasion and corrosion protection.
摘要:
Bright level metal deposits can be obtained on substrates from aqueous acid plating baths containing water soluble salts of the metal to be deposited and at least one surfactant of the formulaROCH.sub.2 CH(CH.sub.3)OCH.sub.2 CH(CH.sub.3)N(H)CH.sub.2 CH.sub.2 COOH (I)or ##STR1## wherein R is an alkyl group containing 10 to 12 carbon atoms; x and y are integers, the sum of which is from 2 to about 20. The aqueous acid plating baths of the invention will preferably contain as a brightening agent, at least one carbonyl-containing compound. These plating baths exhibit low foaming characteristics.
摘要:
Disclosed is a method for the production of electroplated components. In the disclosed method, an edge layer of a component to be coated is subjected to a mechanical treatment in which the edge layer is deformed at least in portions, consequently the structure of the edge layer being modified at least in portions and hydrogen traps being produced in the modified portions of the edge layer.
