ABSTRACT:
Precursor-based methods for the production of metal-matrix composite (MMC) coatings on steel and aluminum substrates for improved wear, corrosion and oxidation resistance have been made. Wire and surface precursors are deposited on the substrate by controlled thermal processing using plasma-arc, laser and high-density infrared radiation. The temperature distribution during the formation for coating is controlled by a real tine adaptive control method. The wire precursors produced by continuous pressure infiltration of SiC or mullite fiber with aluminum were used. Steel substrates double-layer plated with binary metals including nickel and aluminum are also thermal-processed to in-situ produce compound such as nickel aluminide coatings.
