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
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.
