Metallic glasses and nano-structured materials are known for outstanding mechanical and magnetic properties, as well as high temperature oxidation and corrosion resistance.   TAFA’s newly developed arc spray materials, 100MXC and 110MXC, are designed to produce coatings having a combination of amorphous and nano-phase properties.   Compared with other methods of nano-material deposition, such as vapor deposition and plasma spraying, the arc spray process is relatively inexpensive and highly efficient.  This paper presents in-depth research and analysis of the exclusive nanophase wires, a new TAFA arc spray technology, and the resultant improved coating properties.  The effect of heat treatment of the coatings is also discussed.  The coatings are analyzed using advanced characterization techniques such as X-Ray Diffraction (XRD), X-Ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM).  The coating features are correlated with the coating responses: adhesion, hardness, modulus, wear, high temperature oxidation, and corrosion resistance.
