“…Coatings based on transition metal nitrides have proven highly effective in enhancing the performance of cutting tools, dies, and other mechanical components [1,2]. CrN, in particular, has been used to extend the lifespan of components in a wide range of industrial applications due to its high hardness, excellent wear resistance, and good resistance to corrosion and oxidation [3][4][5]. Previous studies reported that doping CrN thin films with Al, Ti, B, or Si can improve their mechanical properties.…”

We investigated the effects of substrate rotation speed on the structural and mechanical properties of CrN/CrAlSiN multilayer coatings produced using high-power impulse magnetron sputtering (HiPIMS) on silicon and high-speed steel (HSS) substrates. Structural analysis and characterization of the multilayer coatings were performed using an X-ray diffractometer (XRD), field emission scanning electron microscopy (FE-SEM), an electron probe microanalyzer (EPMA), and a transmission electron microscope (TEM). The thickness of the bi-layer film depended on the substrate rotation speed, as follows: 12 (1.5 rpm), 9.5 (2 rpm), 6 (3 rpm), 4 (4 rpm), and 3.2 nm (5 rpm). The results revealed that the hardness and coating–substrate adhesion strength increased inversely with the thickness of the bi-layer. TEM analysis revealed smaller columnar structures in thinner CrN/CrAlSiN multilayer coatings. The highest results for hardness (20.1 GPa), elastic modulus (336 GPa), and adhesion strength (77 N) were obtained at a substrate rotation speed of 5 rpm. We also investigated the adhesion properties of the multilayer structures and formulated a hypothesis to explain adhesion strength.

“…Generation of MPS on the coating surface or inserted in the deposited films could disrupt the uniform structure and create defects, pinholes, and voided boundaries. These internal imperfections could provide through-film paths for the electrolyte to accede to the film/substrate interface and result in the formation of galvanic cells and localized galvanic corrosion in the substrate [2,22,30]. Better corrosion resistance in the deposited films could be obtained with the higher thickness and the denser microstructure of multilayer CrN/CrAlN coatings.…”

Multilayer CrN/CrAlN coatings were deposited on the 420-SS by the cathodic arc evaporation system with different duty cycles of bias-voltage. The deposited films were characterized by XRD and FESEM techniques. Mechanical, electrochemical, and surface properties of deposited films were studied by nano-indentation, electrochemical, and AFM analysis. Microstructure investigation confirmed the formation of adhesive and dense nanostructure multilayer film.Increasing the duty cycle led to the decrease in the coating grain size and promoted the hardness to 34.1 ± 4 GPa. A clear reduction of size and distribution of macroparticles was observed by using large repulsive force at a high duty cycle. By increasing the duty cycle, the coating deposition rate was increased from 1.23 to 1.38 µm/h and the surface roughness was decreased from 155 to 70 nm. The lower corrosion current density was obtained for the film applied at the 40% duty cycle (0.59 µA cm −2 ), which was about 10-order of magnitude less than the substrate.

In this study, we present the results of the effect of duplex surface modification of 304-L stainless steel substrates by an electron-beam treatment (EBT) and subsequent deposition of diamond-like carbon coatings on the surface roughness and corrosion behavior. During the EBT process, the beam power was varied from 1000 to 1500 W. The successful deposition of the DLC coatings was confirmed by FTIR and Raman spectroscopy experiments. The results showed a presence of C–O, C=N, graphite-like sp2, and mixed sp2-sp3 C–C bond vibrations. The surface topography was studied by atomic force microscopy. The rise in the beam power leads to a decrease in the surface roughness of the deposited DLC coatings. The studies on the corrosion resistance of the samples have been performed using three electrochemical techniques: open circuit potential (OCP), cyclic voltammetry (polarization measurements), and non-destructive electrochemical impedance spectroscopy (EIS). The measured corrosion potentials suggest that these samples are corrosion-resistant even in a medium, containing corrosive agents such as chloride ions. It can be concluded that the most corrosion-resistant specimen is DLC coating deposited on electron-beam-treated 304-L SS substrate by a beam power of 1500 W.
