Product Description

A new method of covering aluminium and its casting alloys (including Al-Si alloys) with Zn, Cu, Ni, Cr, Sn and other galvanic coverings in standard electrolyzer (galvanic baths) with pH from 2 till *2 Very high corrosive resistance due to the protecting oxide film, which on its own has high protective functions and is a hard undercoat for such hard coverings as Ni or Cr. Possibility of applying any galvanic coverings directly on the aluminium casting alloys with a high silicon maintenance (silumins) A method of chemical satining of aluminium alloys has been developed and implemented at our ***** contrast to generally accepted methods, it has a smaller prime price, works without correction until its complete destruction A process of anodization in the sulphuric acid with addition of some ***** contrast to generally accepted methods, it has a considerably smaller prime price, is easy to use and has a very simple correction (that is based on the surface of a given product). An anodization galvanic bath is not susceptible to the contaminations, which peculiar to similar electrolytes. A process at 5mkm thickness of a film is conducted for about *5minutes at the standard current modes in the range of temperature from 5С to *0С. In contrast to the generally accepted anodization electrolyte, which exposes the defect of metal, the application of our electrolyte enables to mask (to smooth out) the defect of the aluminium surface, ***** has a microsection effect
