“…Multilayer coatings have a wide range of applications being used as X-ray mirrors, monochromators, corrosion and erosion protections and diffusion barriers [1±5]. More recently, multilayer coatings have been used for mechanical application, namely to improve the wear resistance of coated components [3,6,7]. It seems that the wear resistance results from a speci®c favourable combination of hardness and toughness, which is dif®cult to obtain with a single coating [8].…”

Multilayers between ceramic materials and metallic materials can combine the high hardness and wear resistance of the ceramic layers with the toughness and mechanical strength of the metallic layers. This work is aimed at the production and characterisation of tungsten nitride/titanium (or nickel) multilayers. The coatings, deposited by magnetron sputtering, are characterised with respect to their structure, morphology and hardness. The adhesion to the substrate is evaluated by a scratch-test technique, as it constitutes a fundamental prerequisite.The choice of titanium and nickel as interlayering materials was made in order to study the role of materials with elevated plasticity, but with different reactivities. Titanium tends to react chemically with other materials, namely, ferrous oxides and nitrides. Nickel has low chemical reactivity but has the same crystallographic structure as the W 2 N phase. All of the multilayer coatings produced have a total thickness of 4 mm. The hardness of the multilayers, deposited with different ceramic/metal thickness ratios, decreases with the thickness of the ductile metallic layers. When the metal thickness is too high it causes the spalling of the coatings. The optimal medium critical load (65 N) is obtained with a ceramic/metal ratio equal to four. Even though the type of bond is different, the adhesion of the multilayers is not in¯uenced by the substitution of titanium with nickel. The deposition process yields well-adhered and suf®ciently hard multilayer coatings when compared with the ceramic single layers. #

Die Verbesserung des Korrosionsverhaltens wird auf das Unterbrechen der Poren durch Zwischenschichten mit unterschiedlichen Strukturen [21] und die Verringerung der Zugspannungen an der Oberfla Èche zuru Èckgefu Èhrt [22].

“…Coating magnesium alloy surfaces is one possible technique for increasing their mechanical properties. Transition metal nitrides like TiN, VN, AlN, CrN, and their ternary alloys have been successfully used as a wear protective coating material for Mg alloys [1][2][3][4]. Due to its well-known high hardness and low adhesion tendency, TiN is the most frequent coating material for engineering tools and electric components.…”

An extensive study of the surface oxidation process on the properties of TiVN/VN multilayer coatings deposited by RF magnetron sputtering on Mg alloys was performed. TiVN/VN multilayer coatings with a total thickness of 660 nm and different layer numbers of 5, 11, and 33 were oxidized by annealing at 450K under partial oxygen pressure. Electronic, mechanical, and tribological properties of these coatings were characterized by X-ray photoelectron spectroscopy (XPS), scanning electron microscope, nanoindentation measurements, and scratch tester. The experimental results showed that the oxidation of TiVN/VN multilayer coatings leads to better performance in terms of surface roughness, hardness, and wear. The hardness of the coating increased significantly (up to 1400 HV) with the oxidation of the surface due to the release of stresses between each layer after in situ annealing. The decline of the friction coefficient after oxidation can be attributed to the formation of a self-lubricating V 2 O 5 layer on the surface, the presence of which was confirmed by XPS. The findings in this work reveal a new technique for applying a better thin film coating for industrial applications of Mg alloys.
