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 %).
