Description
Summary:Fe31Cr15Mo14C10B10Si5Ti15, as an iron-based TFMG, was provided on a substrate made of 304 SUS and a Si wafer by the magnetic sputtering method at a sputtering power of 147 W. The microstructure, mechanical properties like nanohardness, adhesion strength, and toughness, and corrosion behavior of the metallic glass thin films were examined. The results indicated the formation of an amorphous thin film having a thickness of 753 nm, a nanohardness of 17 GPa, and a satisfactory adhesion value HF1-HF2. Moreover, the fracture toughness of the TFMG was obtained to be equal to 6.14 MPa.m 1/2. The decrease of corrosion current density to 3.09×10–6 A/cm2 and the increase of its polarization resistance to 14,903 Ω.cm2 compared to the substrate showed the high corrosion resistance of the thin film.
