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 t...
