| 摘要 |
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 %). |

1. 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, andwherein 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. |
