“…11b). Similar schematic diagrams were proposed by other authors [23,4]. In addition to the dissolution of the reactive interface layer, an etching process of the CoCrMo substrate was also observed for some pinholes, revealed by small pits in the metal substrate at the location of the pinholes.…”

“…a smaller pH, will promote the pitting phenomena characteristic of this kind of materials. Moreover, it has been reported [15] that the inorganic ions such as HPO 4 2− and H 2 PO 4 − present in the composition of the SBF solution, could be adsorbed on the steel surface, decreasing the interaction between the passive film and the corrosive solution and delaying the pitting initiation [19].…”

“…The failure of a-C:H coatings, when tested by employing tribometers under a ball on disk configuration, have been explained by taking into account different causes such as porosity and pin holes [4,5], which are inherent defects found in the coatings produced by plasma processing, the load carrying capacity of the system [6][7][8], roughness of the coating [9], the absence of interlayers [3,10,11], film thickness and hydrogen dilution in the DLC film [12], wettability of the coating surface in contact with the solution [13] and the chemical nature of the solution [14], among others. This paper reports the results obtained from the study of friction and wear in two corrosive solutions of an a-C:H coating deposited in an industrial facility on a 316L stainless steel substrate, employing an alumina ball as static counterpart.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. This paper reports the results obtained from the study of friction and sliding wear in two corrosive solutions of an a-C:H coating deposited on 316L stainless against an alumina ball, employed as static counterpart. Calculations of the values of the von Mises stresses developed at the coating-substrate interface, as soon as the ball touches the coated sample, and how this state of stress influences the response of the coated system under the corrosion environment, are presented and discussed. The results obtained from these calculations, as well as from the experiments conducted in the present research, are compared with other experiments published in the literature, where a-C:H coatings deposited on different substrates and with different coating architectures were tested in similar corrosive media. It has been determined that in those systems, where the von Mises stress in the coating, found in the vicinity of the interface, exceeds the threshold value of approximately 370 MPa, coating failure with spallation will take place, regardless of the substrate nature on which this coating has been deposited. From this analysis it has been concluded that the coating yield strength is of utmost importance in conferring the a-C:H coated system the required stability in a corrosive solution.
