Thin film metallic glasses: Properties, applications and future

Abstract

In this article, we provide a perspective overview of the iconic properties, recent application-oriented research, and future commercialization opportunities of thin film metallic glasses (TFMGs). A brief review on the preparation and fundamental properties of TFMGs will be given first. TFMGs possess attractive properties such as corrosion resistance, extremely low roughness, and antibacterial characteristics, which give rise to various applications in biomedical devices, sensors, and tribology. Therefore, a number of our representative works will be reviewed to showcase the benefits of TFMGs over traditional materials and processing in these applications. In addition, new perspectives in the research and development of TFMGs and opportunities for commercialization will also be highlighted.

Preparation of Zr-Al-Mo-Cu Single Targets with Glass Forming Ability and Deposition of Thin Film Metallic Glass

“…In contrast to BMG, TFMG exhibits thermodynamic and kinetic stability without composition restrictions. Many studies on application of TFMG in various fields have been conducted [14][15][16][17][18]. However, further investigation of the sputtering target for TFMG deposition is still required.…”

ZnO-NWs/Metallic Glass Nanotube Hybrid Arrays: Fabrication and Material Characterization

“…24,25 Metallic glasses (MGs) feature high yield strength, elastic strain, corrosion resistance, and magnetic permeability as well as good biocompatibility, temperature-independent electrical resistivity, and a large electrochemical surface area for catalytic reactions. [26][27][28] The disordered atomic structure without grain boundaries and temperature-dependent mechanical behavior of bulk MGs (BMGs) facilitates their formation into structures of high geometric complexity from the nanometer scale to a few centimeters without appreciable plastic deformation. 29 Also, BMGs can be patterned at the micro/nano scales to form nanowires or nanotubes for a variety of applications.…”

“…31 Thin-film metallic glass (TFMG) (also known as amorphous metallic alloys) are stable and non-brittle at room temperature, providing excellent ductility, good glass-forming ability, high fatigue strength, and biocompatible. [32][33][34][35] Physical vapor deposition (radio-frequency magneto sputtering) can be used to fabricate TFMG coatings in various thicknesses on a variety of substrate materials, including the polymer composites used in water, oil, and gas separation. 36,37 Pd-based TFMG coating on the silicon substrate (PdCuSi) and hybrid of TFMG with semiconductor material (ZnO-NWs, nanorod and nanotube) can also be used for the detection of hydrogen gas and UV photodetector.…”

Влияние условий магнетронного распыления на структуру Zr-Pd покрытий

“…Однако в перечисленных приложениях требуется нанесение этих материалов в виде тонких покрытий. Тонкие пленки заданного состава могут быть получены посредством магнетронного распыления материалов [9]. При осаждении из газовой фазы достигается особо высокая скорость охлаждения формирующегося материала, необходимая для стеклования некоторых сплавов [10].…”

“…В то же время существует проблема адаптации методов газофазного осаждения для получения пленок с высокой скоростью без потери уникальных свойств. В [9,[11][12][13] [9,[11][12][13]. По этому показателю материал превосходит требования, которые предъявляются к покрытиям на мишенях для термоядерного синтеза.…”
