| titleOfInvention | Method for producing hafnium carbide surfaces on carbon based materials |
| abstract | A method for treating surfaces of carbon based materials produces a layer of hafnium carbide with no significant change of the location of the surface or the dimension of the part being treated. A slurry containing elemental hafnium is applied to this surface. The surface is heat treated in a vacuum furnace, causing the hafnium in the slurry to form an HfC layer within the material, and remove all other slurry materials from the surface. In a variation of the method, the slurry may also contain silicon and chromium to catalyze the reaction. The treated surface exhibits improved properties for components of high temperature gas flow handling systems. The method is useful for valves and ducts having complex internal surface geometries. |
