“…[6,7]. Consequently, numerous studies have focused on characterizing the nanomechanical and tribological properties of MGTFs, which are essential for the development of micro-mechanical and biomedical devices [8][9][10][11]. For instance, as one of the pioneers in this field, Liu et al [12] investigated the tribological behavior of ZrCuAlNi MG films on using micro-scratch techniques.…”

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.

“…Electrodeposition is a facile process for obtaining MG coatings that is attractive because of its simplicity, rapid deposition rate, cost-effectiveness, low-temperature operation, and tuning of composition with enhanced surface properties. − Here, biocompatible Co–P metallic glass coatings were synthesized by a facile electrodeposition approach, and their tribological behavior was evaluated in a simulated physiological environment. There are several studies on the microstructure and wear behavior of Co–P alloys with varying phosphorus content. − However, there are no reports related to their biocompatibility and performance in a physiological environment.…”

Metallic glasses represent a class of metallic alloys with a fully amorphous structure and attractive properties, making them promising in bioimplant applications. Here, the degradation tolerance of biocompatible cobalt−phosphorus (Co−P) metallic glasses was studied in a simulated physiological environment. The metallic glasses were synthesized in the form of coatings through a facile electrodeposition approach. This method utilizes their outstanding surface characteristics and bypasses the size limitations usually associated with their bulk counterparts. The Co−P alloys showed exceptional tribological response with ∼14% lower coefficient of friction and 2 orders of magnitude lesser wear rate compared to SS316 stainless steel. In addition, the Co−P alloys showed a 3 times higher hardness and 4 times higher hardness/ modulus ratio compared to SS316, indicating better elastic recovery under dynamic shear stresses that are common in load-bearing bioimplants. The Co−P metallic glasses exhibited excellent hemocompatibility and cytocompatibility in terms of lower platelet adhesion, spreading, and aggregation, a hemolysis ratio lower than 1%, and enhanced surface wettability, suggesting a superlative performance in bioimplant applications.
