“…Since the commercialization of TiN coatings in 1980s, transition metal nitride hard coatings have been extensively applied in bearings, gears, as well as cutting and forming tools because of their high hardness, good wear, and corrosion resistance [ 1 , 2 ]. Their capability to extend tool lifetime in abrasive and corrosive environments has been verified [ 3 ].…”

In the current study, the properties of the CrxN coatings deposited on the Inconel 718 superalloy using direct current reactive magnetron sputtering are investigated. The influence of working pressure on the microstructure, mechanical, and tribological properties of the CrxN coatings before and after high-temperature hydrogen exposure is studied. The cross-sectional scanning electron micrographs indicate the columnar structure of the coatings, which changes from dense and compact columns to large columns with increasing working pressure. The Cr/N ratio increases from 1.4 to 1.9 with increasing working pressure from 300 to 900 mPa, respectively. X-ray diffraction analysis reveals a change from mixed hcp-Cr2N and fcc-CrN structure to approximately stoichiometric Cr2N phase. After gas-phase hydrogenation, the coating deposited at 300 mPa exhibits the lowest hydrogen absorption at 600 °C of all investigated coatings. The results indicate that the dense mixed cubic and hexagonal structure is preferential for hydrogen permeation resistance due to the presence of cubic phase with higher packing density in comparison to the hexagonal structure. After hydrogenation, no changes in phase composition were observed; however, a small amount of hydrogen is accumulated in the coatings. An increase of coating hardness and elastic modulus was observed after hydrogen exposure. Tribological tests reveal that hydrogenation leads to a decrease of the friction coefficient up to 20%–30%. The best value of 0.25 was reached for hydrogen exposed CrxN coating deposited at 300 mPa.

“…There is also a certain amount of Cr 2 O 3 in the coatings, due to oxygen contamination coming from the sputtering chamber or target composition. In Figure 5(b) , the N spectrum is found in the range of 396.8 ± 0.4 eV, which belongs to CrN phase [ 30 ]. The peaks found in the Cu 2p region are identified as metallic Cu (932.6 ± 0.4 eV) and oxide copper (934 ± 0.4 eV).…”

Influence of Cu Content on the Microstructure and Mechanical Properties of Cr-Cu-N Coatings

et al. 2018

The Cr-Cu-N coatings with various Cu contents (0–25.18 (±0.17) at.%) were deposited on Si wafer and stainless steel (SUS 304) substrates in reactive Ar+N2 gas mixture by a hybrid coating system combining pulsed DC and RF magnetron sputtering techniques. The influence of Cu content on the coating composition, microstructure, and mechanical properties was investigated. The microstructure of the coatings was significantly altered by the introduction of Cu. The deposited coatings exhibit solid solution structure with different compositions in all of the samples. Addition of Cu is intensively favored for preferred orientation growth along (200) direction by restricting in (111) direction. With increasing Cu content, the surface and cross-sectional morphology of coatings were changed from triangle cone-shaped, columnar feature to broccoli-like and compact glassy microstructure, respectively. The mechanical properties including the residual stress, nanohardness, and toughness of the coatings were explored on the basis of Cu content. The highest hardness was obtained at the Cu content of 1.49 (±0.10) at.%.

“…The film and substrate can be considered an unconstrained superposition composite at this temperature, however after the preparation is finished, the temperature cools down to room temperature due to the thermal expansion coefficient between materials. The difference causes various thermal shrinkage tendencies, but because the film and the substrate are constrained at the interface, the varied shrinkage tendencies induce the production of residual stress inside the film, which is created during the nucleation and growth of the film [20]. The causes of intrinsic stress are multifaceted, and there is no obvious mechanism for its production.…”

The ability to monitor fractures is based on the integration of PVD thin film sensors and substrates, and the interface stress distribution of the sensor under load which directly impacts the bonding performance. This research analyzes the impact of film elastic modulus and thickness on film-substrate interface stress using the Abaqus software to investigate the influence of PVD film sensor material properties on the film/substrate interface stress distribution. The higher the concentration of interfacial tension, the thicker the layer. The sensor's structural parameters were optimized and significantly enhanced crack detecting sensitivity. The results reveal that the PVD film sensor material can detect structural defects efficiently. The conclusions established in this work have some implications for the optimal design of PVD thin film sensors.
