Title:
亜鉛被膜または亜鉛合金被膜のめっき堆積のためのシアン化物を含まない水性アルカリ浴
Document Type and Number:
Japanese Patent JP4263363
Kind Code:
B2
Abstract:
An aqueous alkaline cyanide-free bath for the galvanic deposition of zinc or zinc alloy coatings on substrate surfaces is described, which contains in addition to a source of zinc ions and optionally a source of further metal ions, also hydroxide ions and a polymer of the general formula A that is soluble in the bathas well as optionally conventional additives. The bath may furthermore contain a quaternary derivative of a pyridine-3-carboxylic acid of the formula B and/or a quaternary derivative of a pyridine-3-carboxylic acid of the formula CA process for the galvanic deposition of zinc coatings and zinc alloy coatings using the aforedescribed bath is also described.By using the baths according to the invention it is possible to produce coatings that exhibit a uniform layer thickness combined with a high gloss, and which do not exhibit any tendency to exfoliate.
