摘要：

TiN and Ti coatings were deposited by d.c. magnetron sputtering on a Zn-Al-Cu alloy. The coatings were deposited at a relative low temperature of 115-130 degrees C. X-ray diffraction showed that the films were crystalline. A pure titanium interlayer was used to improve the adhesion and corrosion resistance of the titanium nitride films. The corrosion behavior of samples in NaCl solutions was studied using polarization curves. Scanning electron microscopy was used to study the corroded samples. It was found that corrosion resistance of coated ahoy was higher than the substrate resistance. Furthermore the corrosion resistance is mainly controlled by the presence of defects in the TiN and Ti films. (C) 1998 Elsevier Science S.A. All rights reserved.
