Patent ID: 8778459

Claim:
A method of coating a surface, said method comprising the steps of: feeding a first set of amorphous metal particles from a first source, wherein the composition of said first set of amorphous metal particles is an Fe-based alloy, Ni-based alloy, Cu-based alloy, Al-based alloy, or Zr-based alloy, further alloyed with each 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 %, and carbon≧4 atomic %; feeding a mixture of ceramic particles and second set of amorphous metal particles, wherein said mixture is fed from a second source, wherein the composition of said ceramic particles is an oxide, carbide, boride, or nitride, and wherein said the particle size of said ceramic particles is within the range of 5 nanometers to 5 microns; combining the said fed first set of amorphous metal particles and said fed mixture, to form a combined mixture; feeding said combined mixture into a spray deposition device; and, applying said combined mixture to the surface by a spray process, thereby coating the surface with a coating of a homogenously mixed composite material made of said first set of amorphous metal particles, said second set of amorphous metal particles, and said ceramic particles.
