Claims
- 1. The method of forming an adherent co-deposit of hexagonal alpha titanium oxide Ti.sub.2 O.sub.3 and alpha alumina Al.sub.2 O.sub.3 on a wear surface comprising the steps of
- (a) maintaining said surface at a temperature between about 900.degree. and 1250.degree. C, and
- (b) contacting said surface with a gaseous reactant stream containing an aluminum halide, water vapor and a titanium halide.
- 2. The method set forth in claim 1 wherein said aluminum halide is AlCl.sub.3 and said titanium halide is TiCl.sub.4.
- 3. The method set forth in claim 1 wherein said reactant stream is formed by
- (a) reacting CO.sub.2 and H.sub.2 in a carrier gas to form H.sub.2 O,
- (b) mixing said aluminum halide with said carrier gas and the reaction products to form a first reactant stream,
- (c) forming a second reactant stream containing said titanium halide, and
- (d) mixing said first reactant stream and said second reactant stream in the vicinity of said surface.
- 4. The method set forth in claim 3 wherein said carrier gas is argon and said first reactant stream is maintained at a temperature between about 370.degree. and about 410.degree. C.
- 5. The method set forth in claim 4 wherein said first reactant stream is conducted to the vicnity of said surface through a first nozzle and said second reactant stream is conducted to the vicinity of said surface through a second nozzle, said first and second nozzles terminating relatively near said surface and mixing said first and second reactant streams in the immediate vicinity of said surface.
