Unlike the direct deposition of ceramic multilayers, we prepared a Mo/W multilayer film on a Mo substrate using magnetron sputtering and then carburized the sample to obtain a Mo₂C/W₂C ceramic multilayer film. The simplest ceramic three-layer film is the main research object of this work. Our study shows that, during the carburization, the carbide layers grew inward with two ceramic/metal carburization frontiers, with the Mo₂C/Mo frontier leading the W₂C/W frontier. W₂C can grow epitaxially on the Mo₂C grains without nucleation, forming columnar grains of half Mo₂C and half W₂C across the interlayer interface. The ceramic three-layer film was nonporous, and there was a significant interdiffusion of Mo and W elements at the interlayer interfaces, and the final film-substrate interface was the Mo₂C/Mo interface located inside the initial Mo substrate. The hardness of the ceramic film with a thickness of 5.5–7.5 μm was about 1500–1600 HV.

The pretreatment prior to PVD processes directly influences the adhesion and consequently the overall performance of the coating system. Therefore, different approaches such as bias based glow discharges (GD) and metal ion etching (MIE) methods are commonly conducted, which are however on the one side strongly limited in their etching rate as well as in their adaptability and on the other side lead to macro defects on the surface of the substrate reducing the performance of the coated tools. To overcome these challenges an improved etching process, which combines the high plasma density of cathodic arc evaporation with a noble gas-based glow discharge called advanced Arc Enhanced Glow Discharge (AEGD) is used.

Additionally, for tool steels an adjusted composition of the plasma allows the nitriding of the surface near region, which leads to a graded hardness increase without forming a compound layer. The adhesion of the subsequently deposited coating was improved by the diffusion process due to the higher load carrying capacity.

Their potential as an effective solution to address the issue of glass delamination in the pharmaceutical industry has been explored. Thanks to the combination of RBS, NRA and ERDA, the thickness loss and the evolution of the elemental composition throughout alteration were successfully trucked. Based on these parameters alongside the structural and bonding state investigations, the films were classified into 3 groups, each exhibiting distinct behavior. The first group, with zero (silica) or very low concentrations of N and C, completely dissolved into the solution via hydrolysis. The second group consisted of films with higher rates of O substitution by N and C ranging between 0.25 and 0.77, which experienced partial thickness loss and depletion of N and O from the network. This led to a relative increase in C concentration beneficial to the films alteration resistance. The final group included the most durable films, characterized by a substitution rate higher than 1. These films did not experience any thickness loss despite the aggressiveness of the chemical medium. For (N + C)/O ratios of ≥1.2, there was no alteration in composition, structure and bonding state. For lower values, oxidation starts to manifest, which seemed to be slowed down by the further presence of carbon in the film. These characterizations enabled also the provision of logical explanations for the complex variations in hardness and elasticity observed post-alteration, as measured by nanoindentation. In parallel with these chemical performances, the SiOxNyCz systems exhibit a range of Young's modulus and hardness that can reach 127.5 and 9.2 GPa respectively, depending of the oxygen substitution level. Films with higher nitrogen and carbon content show no reduction in hardness and maintain better elastic properties after exposure to the aqueous solution. Films depleted from N and O after alteration become harder when they dispose of an initial high C concentration. This comprehensive approach not only advances our understanding of the durability of silicon oxycarbonitride films but also underscores the significant influence of initial compositional and structural attributes on their performances under extreme conditions. By classifying the tested films into different families based on their degradation behaviors, we were able to offer a clear perspective on the factors that contribute to the major robustness of these materials.
