“…It is clear that the value of friction coefficient is about 0.062 for the nonannealed, while for the MG, it was annealed for 60 min, and the coefficient of friction slightly decreased (<0.03) under 0.9 μN applied force. The friction coefficient decreases with increasing annealing time in both conditions, which is in line with previous reports, 39 demonstrating the possibility of reduction of friction coefficient by tuning the surface patterning with aging temperature. 13 It is reported that most of the frictional work during the wear process creates heat energy, which modifies the tribological behaviors of Nanoscratched surfaces, such as forming delocalized free metal ions for chemical reordering or even heating interfacial contact materials.…”

A new and unique alloy formulation design strategy has been developed in order to fabricate thin-layered metallic glasses (TLMGs) with superior fracture resistance and low coefficient of friction (COF) during the nanoscratching test. Due to the outstanding properties, TFMG could be applied for different uses, such as for surface coating, biomedical, bioimprinting, electronic devices, spacecraft, and railway, all of which need surface fracture resistance. The fabricated Zr-based metallic glass was prepared from Zr, Al, Cu, Ni, and Ag above 99.9 Wt % in purity by arch melting techniques. TFMGs were coated on silicon wafer by sputtering the vapor deposition method from bulk metallic glass then annealed below glass transition temperature T g ∼ 450 °C for 10, 30, and 60 min. Nanoindentation and nanoscratch tests were used to investigate nanomechanical and nanotribological properties, and atomic force microscopy (AFM) was used to examine the surface morphology and microstructures of TLMG. The nanoindentation data indicated that the average hardness of metallic glasses increased from 9.75 (as-cast MG) to 13.4 GPa (annealed for 60 min). Coefficients of friction for the cast sample, annealed for unannealed, 10, 30, and 60 min, were 0.062, 0.049, 0.039, and 0.03, respectively, as well as the wear depths were 201. 56, 148.43, 37.32, and 25.27 nm, respectively. These studies show that the coefficient of friction and wear rate decreases when the annealing time increases as a result of atomic reordering and structural relaxation that occurred at longer annealing times. Furthermore, continuous wear process, wear depth, wear track volume, and contact area decrease with increasing annealing time. This study can be used to design protocols to prepare novel TLMGs, which have outstanding mechanical and tribological properties for engineering materials applications.

A new and unique alloy formulation design strategies has been developed in order to fabricate thin layered metallic glasses (TFMG) with superior fracture resistance and low coefficient of friction (COF) during nano-scraching test. Due to the outstanding properties, TFMG could be applied for different uses uch as surface coating, biomedical, bio implant, electronic devices, spacecraft and railway, all of which need surface fracture resistance. The fabricated Zr-based metallic glass having the composition of Zr60Cu25Al5Ag5Ni5 (at.%) was annealed for 10, 30, and 60 min below the glass transition temperature. Nanoindentation and nanoscratch tests were used to investigate mechanical and nanotribological properties. Atomic force microscopy (AFM) was used to examine the surface morphology and microstructures. The annealing effect and applied forces change over the chemical structure and stability, morphological change, elastic modulus, hardness, wear rate, and coefficient of friction of the samples were systematically investigated. The nano-indentation data indicated that the hardness and average elastic modulus of the samples increased with increasing annealing time, compared with those of the as-cast MG. More intriguingly, the coefficient of friction and wear rate decreases when the annealing time increases compared to as-cast MG. Furthermore, the continuous wear process, wear depth, wear track volume, and contact area decreases with increasing annealing time, as a result of the improvement of the mechanical and tribological properties of the thin-layered MGs. This study can be a reference to the design protocol to prepare novel a-MGs, which have outstanding mechanical and tribological behavior for engineering material applications.
