surface treatment techniques, such as physical vapor deposition (PVD), chemical vapor deposition (CVD), sol-gel methods, anodic oxidation, have been attempted to improve the wear or corrosion resistance of Ti and Ti alloys [4,5]. However, these methods have their own limitations. For instance, the films deposited onto Ti alloys using PVD or CVD methods are often very thin and suffer from poor adhesion......
and a low friction coefficient. At present, TiN coatings are mainly obtained by physical vapour deposition (PVD) or chemical vapour deposition (CVD) [1,2]. However, their deposition efficiency..., without the characteristic brittleness of pure TiN coatings obtained by PVD or CVD techniques. Moreover, considerable thickness (>200 μm) can be fabricated within a few minutes of deposition. Compared......

Therefore, the achieved deep drawing results of this study are also compared to former deep drawing results using PVD-Al-Sc foils to evaluate the suitability for industrial application......

, such as surface hardening process, anodizing, plating, spraying and physical vapor deposition (PVD), are usually used to form the passivation layer films on the surface of magnesium alloys. However, thin films prepared using these methods are normally insufficient in machine parts used under harsh conditions. For example, vapor coatings by PVD are too thin to endure under large stress. The adherence......
