A method is provided for manufacturing an article. The method comprises depositing by additive friction stir deposition a wear-resistant material on a surface of a preform to provide an intermediate article. The preform comprises a first composition and the wear-resistant material comprises a second composition. The second composition is substantially different from the first composition. The method also comprises machining the intermediate article to remove therefrom at least a portion of the wear-resistant material.
