Applications Thermal Spray Coatings and Applications Therefor. This invention relates to coatings for a metal or non-metal substrate comprising (i) a thermal sprayed bondcoat layer applied to said substrate comprising an alloy of MCrAlM0 wherein M is an element selected from nickel, cobalt, iron and mixtures thereof, and M0 is an element selected from yttrium, zirconium, hafnium, ytterbium and mixtures thereof, and wherein M comprises from about 35 to about 80 wt.% of said alloy, Cr comprises from about 15 to about 45 wt.% of said alloy, Al comprises from about 5 to about 30 wt.% of said alloy, and MÕ comprises from about 0.01 to about 1.0 wt.% of said alloy, said alloy thermally sprayed from a powder having a mean particle size of 50 percentile point in distribution of from about 5 to about 100 lm, said bondcoat having a surface roughness of at least 200 micro-inches, and said bondcoat having a thermal expansion of about 6.5 mm per meter or less between a temperature of from about 25 °C to about 525 °C, and (ii) a thermal sprayed ceramic layer applied to said bondcoat layer; wherein said coating has a helium leak rate of less than 6 9 106 standard cubic centimeters per second. The coatings are useful for extending the service life under severe conditions, such as those associated with metallurgical vesselsÕ lances, nozzles and tuyeres. CA 2678361: Prasad S. Apte, J. P. Meaghe, and Shawn W. Callahan.
Journal of Thermal Spray Technology
Company: Praxair Technology Inc. Issued/Filed: January 15, 2013/February 15, 2008. Piston Ring. Provided is a piston ring having a thermal sprayed laminated coating tightly adhering thereto, which coating is excellent in wear resistance and scuffing resistance as well as less damaging to a mating material. The piston ring having a thermal sprayed base layer formed by thermal spraying of a mixed powder including at least Mo powder, Ni-based self-fluxing alloy powder and Cu and/or Cu alloy powder; and a thermal sprayed surface layer including Cu, which is formed on a sliding surface of the piston ring after forming the thermal sprayed. The thermal sprayed base layer at least includes 50-80% by mass of Mo, 1-12% by mass of Cu and/or Cu alloy, and a remainder: Ni-based self-fluxing alloy, the area ratio of Cu and/or Cu alloy phase which appears on the sliding surface of the thermal sprayed base layer is 0.5-15%, and the thermal sprayed surface layer includes 70-100% by mass of Cu.
