Abstract (en)

[origin: WO2007048513A2] Disclosed is a method for producing corrosion-resistant, painted oxide layers on aluminum or aluminum alloys. According to said method, a polysilazane solution is applied to a dry oxide layer that is painted with a water-soluble, anionic color, and the coating is then hardened at a temperature ranging from 40 to 150<SUP>o</SUP>C.
