  • Method of producing a pre-alloyed stabilized zirconia powder
    Patent number: 6869550
    Abstract: A pre-alloyed stabilized zirconia powder suitable for use in thermal barrier applications is formed by alloying zirconia with a stabilizer, such as yttria, and processing the alloyed stabilized zirconia to form a very fine powder. The raw powder is then spray-dried to produce an agglomerated powder having an average particle size suitable for use in spray coating applications. The resulting powder can be used in a thermal-spray application to produce a porous thermal barrier coating having a substantially decreased thermal conductivity when compared to conventional TB coatings, such those produced using plasma-densified powders.
    Type: Grant
    Filed: December 7, 2001
    Date of Patent: March 22, 2005
    Assignee: Sulzer Metco (US) Inc.
    Inventors: Mitchell R. Dorfman, Luis F. Correa, Christopher G. Dambra, Komal Laul, Richard K. Schmid

  • Method for preparing a thermal spray powder of chromium carbide and nickel chromium
    Patent number: 6254704
    Abstract: A thermal spray powder consists of nickel, chromium and carbon. The chromium consists of a first portion and a second portion, the nickel being alloyed with the first portion in an alloy matrix. The second portion and the carbon are combined into chromium carbide substantially as Cr3C2 or Cr7C3 or a combination thereof, with the chromium carbide being in the form of precipitates between 0.1 &mgr;m and 5 &mgr;m distributed uniformly in the alloy matrix.

  • Powder of chromium carbide and nickel chromium
    Patent number: 6071324
    Abstract: A thermal spray powder consists of nickel, chromium and carbon. The chromium consists of a first portion and a second portion, the nickel being alloyed with the first portion in an alloy matrix. The second portion and the carbon are combined into chromium carbide substantially as Cr.sub.3 C.sub.2 or Cr.sub.7 C.sub.3 or a combination thereof, with the chromium carbide being in the form of precipitates between 0.1 .mu.m and 5 .mu.m distributed uniformly in the alloy matrix.
