Abstract
An article coated with a highly durable, wetting resistant coating is provided. The article comprises a coating that comprises a cermet material. The cermet material includes a nickel-bearing metal matrix and a phase disposed within the matrix. The phase includes an anion moiety, for example nitrogen, carbon, or boron; and a cation moiety, for example chromium, zirconium, titanium, vanadium, hafnium, niobium, or tantalum. The phase is present in the cermet at a level of at least about 5 volume %.
Claims46
An article, comprising:
- a coating comprising a cermet material, the cermet material comprising:
- a metal matrix comprising nickel;
- and a phase disposed within the matrix, the phase comprising an anion moiety and a cation moiety wherein the anion moiety comprises nitrogen, carbon, boron or a combination thereof, and the cation moiety comprises zirconium, titanium, vanadium, hafnium, niobium, or tantalum or combinations thereof;
- wherein the phase is present in the cermet at a level of at least about 5 volume %.
An article, comprising:
- a coating comprising a cermet material, the cermet material comprising:
- a metal matrix comprising nickel wherein the content of chromium is less than about 10 wt % of the matrix;
- and a phase disposed within the matrix, the phase comprising carbon, nitrogen or boron or combinations thereof and a cation moiety wherein the cation moiety comprises chromium, zirconium, titanium, vanadium, hafnium, niobium or tantalum or combination thereof.
A device comprising:
- a chamber enclosing a fluid flow path between an inlet and an outlet;
- and
- a surface disposed within the flow path, the surface comprising a cermet material, wherein the material comprises
- a metal matrix comprising nickel;
- and
- a phase disposed within the matrix, the phase comprising an anion moiety and a cation moiety wherein the anion moiety comprises nitrogen, boron, or carbon, or a combination thereof, and the cation moiety comprises chromium, zirconium, titanium, vanadium, hafnium, niobium, or tantalum or combination thereof.
