Filed:

Nov 12, 1974

Appl. No.:

5/523018

Inventors:

John E. Gates - Worthington OH
Neil D. Veigel - Novi MI
Melvin F. Browning - Columbus OH

Assignee:

Aerospace Materials Inc. - Columbus OH

International Classification:

B32B 1504

US Classification:

29195

Abstract:

Composite coatings are formed of a ceramic-type material such as chromium carbide over an intermediate layer of a ductile metal such as nickel on stainless steel turbine compressor blades. Such coatings were found to reduce the erosion by entrained particles to less than 10 percent that experienced by uncoated blades.

Abstract:

A method of coating ceramic nuclear fuel particles containing a major amount of an actinide ceramic in which the particles are placed in a fluidized bed maintained at ca. 800. degree. to ca. 900. degree. C. , and niobium pentachloride vapor and carbon tetrachloride vapor are led into the bed, whereby niobium metal is deposited on the particles and carbon is deposited interstitially within the niobium. Coating apparatus used in the method is also disclosed.
