“…TFMGs are a class of amorphous metal materials with excellent properties such as high strength, high toughness, high wear resistance, excellent conductivity and chemical stability, and have a wide range of application prospects in engineering and scientific fields [ 126 , 164 , 165 ]. In the process of preparing TFMGs from PVD, the target material is sublimated into a gaseous substance under a high vacuum environment, and then deposited on the substrate surface to form a thin film [ 125 , 126 , 160 , 165 , 166 ]. By adjusting the PVD process parameters, such as deposition rate, temperature, pressure, atmosphere, etc., the structure and properties of TFMGs films can be accurately controlled, which provides new ideas and approaches for the large-scale preparation and application of TFMGs.…”

“…At the same time, as a high environmental pollution technology, chromium plating in many industries has been restricted and gradually eliminated. Physical Vapor Deposition (PVD) technology has been reported as one of the most environmentally friendly and efficient technologies for the preparation of ultra-thin coatings [6,7]. Li et al [8] deposited CrN multi-layer coatings on AISI 4140 steel, and the coatings exhibited excellent wear resistance properties.…”

A novel CrCx/C-Cr multilayer coating for cotton picking spindle was prepared on 20CrMnTi substrate by PVD technology. Compared with the traditional electroplated chromium coating, the CrCx/C-Cr coating has dense structure, and no micro-cracks were observed on the surface. The results of nanoindentation show that the nano-hardness of CrCx/C-Cr coating is about 8.46 GPa and 78.5% higher than that of the substrate. Compared with electroplated chromium coating, PVD coating has lower friction coefficient and wear rate, which indicates a better wear resistance property. The multilayer PVD coating provided is expected to replace the high-pollution chromium coating for cotton picking spindle.

“…They observed that film thickness, modulation ratio, and layer patterns significantly influenced the mechanical behavior of the films. In another investigation [18], a fully amorphous CrCoNbB TFMG was fabricated and characterized, which exhibited higher hardness, lower surface roughness, and lower coefficient of friction (COF) compared to sputter-deposited chromium (Cr) coating. Wang et al [19] reported that the ZrCuNiAl metallic glass thin film (MGTF) with a homogeneous structure exhibited higher hardness and lower stiffness compared to its heterogeneous counterpart.…”

Over recent years, metallic glass thin films (MGTFs) have found extensive applications in advanced micro-engineering systems. Consequently, there is a need to thoroughly assess the nanomechanical and tribological behaviors of MGTFs to optimize the design of efficient components. In this study, we employed the nanoindentation technique in various modes to investigate the elastic heterogeneity, tribological response, and mechanical properties of CuZr amorphous films. Before conducting the mechanical tests, annealing treatments at 500 K and 600 K were performed to create samples with different stored energies. The thermal history analysis revealed that the annealing process reduced the stored energy in the microstructure. Furthermore, the pre-annealing treatment resulted in increased hardness and Young's modulus of the thin films. Additionally, higher annealing temperatures significantly improved the wear resistance of the MGTFs. Observing the serration dynamics in the scratching test, we noticed that the annealing treatment induced larger shear bands on the wear track side. Moreover, the increase in annealing temperature led to a reduction in elastic heterogeneity, which was consistent with the enthalpy relaxation values in the samples. This suggests that the annealing temperature enhanced the densely packed atomic structure, leading to the stabilization of the thin films.
