  • Corrosion resistant amorphous metals and methods of forming corrosion resistant amorphous metals
    Patent number: 8778459
    Abstract: A system for coating a surface comprises providing a source of amorphous metal, providing ceramic particles, and applying the amorphous metal and the ceramic particles to the surface by a spray. The coating comprises a composite material made of amorphous metal that contains one or more of the following elements in the specified range of composition: yttrium (?1 atomic %), chromium (14 to 18 atomic %), molybdenum (?7 atomic %), tungsten (?1 atomic %), boron (?5 atomic %), or carbon (?4 atomic %).
    Type: Grant
    Filed: October 1, 2009
    Date of Patent: July 15, 2014

  • Process for making corrosion-resistant amorphous-metal coatings from gas-atomized amorphous-metal powders having relatively high critical cooling rates through particle-size optimization (PSO) and variations thereof
    Publication number: 20070107809
    Abstract: A system for the deposition of full-density, pore-free, corrosion-resistant, thermal-spray amorphous-metal coatings for the protection of a less corrosion resistant substrate. The system comprises using particle-size optimization (PSO) to ensure that the amorphous metal particles are small enough to ensure that the critical cooling rate is achieved throughout the amorphous metal particles.
