ABSTRACT:
An extension is formed directly on the end of an article by dipping the end into a molten bath of an alloy, followed by withdrawal of the end at a rate sufficient to form the extension. Extensions formed have a microstructure that is continuous and compatible with that of the article. Such microstructures may include epitaxial growth of the extension onto the microstructure of the article. The method establishes a temperature gradient within the article that may be controlled by heating and/or cooling the article during the practice of the method.
