  • Self-bonding MCrAly powder
    Patent number: 6410159
    Abstract: A material useful for forming high temperature coatings. The material contains a MCrAlY powder wherein M is selected from the group consisting of iron, nickel, cobalt, iron-base alloys, nickel-base alloys and cobalt-base alloys. An aluminum layer coats the powder. The method forms a high temperature coating with the powder. Thermally spraying the MCrAlY powder towards a substrate reacts the aluminum coating with the MCrAlY powder to metallurgically bond the MCrAlY powder and coat the substrate.

  • Wear-resistant quasicrystalline coating
    Patent number: 6254699
    Abstract: A thermally sprayed coating formed with a quasicrystal-containing alloy, the alloy consisting essentially of, by weight percent, 10 to 45 Cu, 7 to 22 Fe, 0 to 30 Cr, 0 to 30 Co, 0 to 20 Ni, 0 to 10 Mo, 0 to 7.5 W and balance aluminum with incidental impurities. The alloy contains at least 50 weight percent &psgr; phase. The coating has a macro hardness of at least HR15N 75.
