Microstructure, mechanical and anti-corrosion property evaluation of iron-based thin film metallic glasses

摘要: Abstract Thin film metallic glasses (TFMGs) represent a class of promising engineering materials for structural applications. Despite the effort that has been made in development TFMG materials, iron-based thin fabricated by sputtering have gained limited attention. In this work, five Fe–Zr–Ti with different Fe contents ranging from 37.6 to 49.8 at.% were prepared magnetron co-sputtering system using pure Fe, Zr and Ti targets. Through XRD TEM analyses, amorphous phase was confirmed each coating. The glass transition temperature (Tg) crystallization (Tx) increased increasing content reached 963 K 989 K, respectively, when 49.8 at.%. supercooled liquid region around 26.3 51.6 °C, which shown be unrelated concentration. hardness, elastic modulus, H/E ratio TFMGs Based on HRC-DB test, adequate adhesion quality obtained all TFMGs. corrosion resistance also spontaneous passivation behavior discovered due large valve metals. Nevertheless, strongly influenced surface defects. A series high hardness good property reported study.
