GAS PHASE DEPOSITION OF ALUMINUM USING A COMPLEX ALUMINUM HALIDE OF AN ALKALI METAL OR AN ALKALINE EARTH METAL AS AN ACTIVATOR ABSTRACT OF THE DISCLOSURE A gas phase aluminizing process for alloys based on Group VI B and VIII metals such as chromium, iron, cobalt and nickel is disclosed. The process is particularly useful in the coating of internal passages of complex high temperature gas turbine hardware such as blades and vanes, where it has been found that the complex aluminum halide activators used herein have a "throwing power" greater than was heretofore obtained with the conven- tional halide activators such as ammonium chloride in the gas phase process.
