摘要：

In order to use brass coloured decorative coatings for outdoor applications and sanitary fittings which are exposed to highly corrosive environments the corrosion resistance of reactively sputtered ZrN coatings is investigated. The colour stability of ZrN layers is used to characterize the corrosion resistance after testing. It has been shown that the morphology of reactively sputtered ZrN layers affect the corrosion resistance and hence the stability of the colour. The corrosion resistance increases with decreasing grain size and surface roughness. However, it was not possible to avoid corrosion completely by changing the structure of the ZrN films. For complete corrosion resistance of ZrN coatings, a new layer system based on ZrN was developed. Leaving the brass colour unchanged the new layer system possesses a high corrosion resistance and also improves the wear resistance of ZrN. (C) 1999 Elsevier Science S.A. All rights reserved.
