“…The W-C:H films were deposited using unbalanced magnetron sputtering in an argon/acetylene atmosphere in a Hauzer HTC-1000 production scale coating system, as described by Strondl et al in Refs. [9] and [10]. The films have a thickness of 2 Am with an adhesive intermediate chromium layer of 200 nm.…”

“…The microstructure of a-C:H:W obviously becomes less pronounced as the ethine flow rate, respectively the volume fraction of the a-C:H matrix, increases. It is noteworthy that none of the depicted a-C:H:W variants shows nanolayers of a periodically alternating W/C ratio, as they can result from the discontinuous contribution of the sputtering process to coating growth due to substrate rotation [10,30,31]. Hence, it can be concluded that, for the a-C:H:W coatings deposited within the scope of this study, the frequency of substrate rotation was sufficiently high, so as to obtain a homogeneous coating composition, which is an optimal prerequisite for the assessment of representative mechanical properties by nanoindentation.…”

Tungsten-modified hydrogenated amorphous carbon coatings (a-C:H:W) were deposited on high speed steel by reactive magnetron sputtering of a tungsten carbide target in an argon-ethine atmosphere. The deposition parameters, sputtering power, bias voltage, argon and ethine flow rate, were varied according to a central composite design comprising 25 different parameter combinations. For comparison, a tungsten carbide coating was deposited, as well. During coating deposition, the process variables, total pressure, sputtering voltage and bias current, were measured as process characteristics. The thickness of the deposited coatings was determined using the crater grinding method, and the deposition rate was calculated. Young's modulus E and indentation hardness H IT were characterized by means of nanoindentation. With E = 80 − 253 GPa and H IT = 7.8 − 22.0 GPa, the mechanical properties were found to vary strongly in between different a-C:H:W variants. Using statistical methods, it is shown that these properties, as well as the deposition rate significantly depend on all four varied parameters. Despite a very similar influence of the parameters on modulus and hardness, as well as a very strong correlation of both properties, it is pointed out statistically that the H/E ratio, which is an indicator of the wear resistance, can be adapted in a targeted way and with some degree of independence.

“…There are only a few studies on the structural and mechanical properties of multilayer DLC/BN films. The structural and mechanical properties of multilayer films depend on the composition, number of interfaces and bilayer thickness [10]. A large number of internal interfaces aligned parallel to the substrate surface can retard crack propagation and provide barriers to dislocation movement [11].…”

In this article, the results obtained from a study on multilayer diamond-like carbon and boron nitride (DLC/BN) films are reported. The microstructure, atomic concentration, hardness and friction coefficient of the films were characterized using transmission electron microscopy, auger electron microscopy, nano-indentation measurements and ball-on-disk friction testing. The effects of bilayer thickness and substrate bias on film growth were investigated. All multilayer films showed alternate DLC and BN layers, except the 2-and 4-nm bilayer of multilayer DLC/BN films deposited without substrate bias. Although the layers were very thin, each layer was distinguishable. This was confirmed by the use of TEM imaging and AES measurements. The hardness values of all the multilayer films were lower than those measured for the monolayer DLC and BN films. However, the hardness can be altered with a change in the bilayer thickness. Furthermore, in the case of the films deposited with substrate bias, multilayer DLC/BN films showed an improvement in wear resistance compared to monolayer DLC and BN films. Thus, the deposition of multilayer DLC/BN films can be considered to be beneficial in prolonging the service life of the surface.
