摘要:
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.
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 %).
摘要:
The invention provides oxidation resistant coatings for transition metal substrates and transition metal alloy substrates and method for producing the same. The coatings may be multilayered, multiphase coatings or gradient multiphase coatings. In some embodiments the transition metal alloys may be boron-containing molybdenum silicate-based binary and ternary alloys. The coatings are integrated into the substrates to provide durable coatings that stand up under extreme temperature conditions.
