“…The measurement of full Debye-Scherrer rings then allows texture to be measured (or at least estimated) from the azimuthal intensity distributions, and residual stresses to be determined from the distortion of the rings. This approach has since been used to measure important characteristics, including residual stress distribution, in a multitude of different coating systems such as TiN (Daniel et al, 2014;Meindlhumer et al, 2020a), (Ti,Al)N (Riedl et al, 2014;Zalesak et al, 2016a,b;Ba ¨cke et al, 2023), TiAlON (Schalk et al, 2019), CrN (Daniel et al, 2013;Bartosik et al, 2013;Daniel et al, 2015), Cr-Al-C (Heinze et al, 2023), TiW (Saghaeian et al, 2019), TiB (Schalk et al, 2014), Al 2 O 3 (Tkadletz et al, 2015), diamond (Gruber et al, 2019;Hinzmann et al, 2021) and different multilayers (Bartosik et al, 2015;Keckes et al, 2018;Tkadletz et al, 2018;Ja ¨ger et al, 2019;Klima et al, 2019).…”

The use of hard X-ray transmission nano- and microdiffraction to perform in situ stress and strain measurements during deformation has recently been demonstrated and used to investigate many thin film systems. Here a newly commissioned sample environment based on a commercially available nanoindenter is presented, which is available at the NanoMAX beamline at the MAX IV synchrotron. Using X-ray nanoprobes of around 60–70 nm at 14–16 keV and a scanning step size of 100 nm, we map the strains, stresses, plastic deformation and fracture during nanoindentation of industrial coatings with thicknesses in the range of several micrometres, relatively strong texture and large grains. The successful measurements of such challenging samples illustrate broad applicability. The sample environment is openly accessible for NanoMAX beamline users through the MAX IV sample environment pool, and its capability can be further extended for specific purposes through additional available modules.

“…However, the brittleness and the lack of ductility of Si 3 N 4 will lead to a drawback of the as-deposited diamond coating that is prominently susceptible to fracture failure [11,12]. Meanwhile, diamond coatings on WC-Co and Si 3 N 4 substrates present a great difference in adhesive strength and creak propagation [13,14].…”

Substrate has an essential influence on the growth process of diamond grains and the quality of the diamond coating. In this paper, the diamond coatings on Co-cemented tungsten carbide (WC-Co) and silicon nitride (Si3N4) substrates were deposited by hot filament chemical vapor deposition (HFCVD) technique to study the effect of growth process on adhesive strength of coating. The WC-Co and Si3N4 substrates were treated by etching and polishing process, respectively. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Raman spectroscopy were used to characterize the diamond coatings. Furthermore, the adhesive strength and tribological properties of the as-deposited diamond coatings were evaluated by indentation tests and dry sliding tests. The results showed that the diamond coating deposited on WC-Co had a considerable stronger adhesive strength and a higher friction coefficient than that on Si3N4, which may partly result from the flat surface morphologies of Si3N4 substrate that was due to no etching pretreatment. Thereafter, a novel etching method for Si3N4 surfaces by hydrofluoric acid (HF) was proposed to roughen the surface, and a new diamond coating with enhanced adhesive strength was fabricated on Si3N4. Hence, for the hard substrate, etching the surface, rather than polishing the surface, played an importance role on improving the adhesion strength of diamond coating.
