摘要： The invention encompasses a method of bonding a first mass to a second mass. A first mass of first material and a second mass of second material are provided and joined in physical contact with one another. The first and second masses are then diffusion bonded to one another simultaneously with the development of grains of the second material in the second mass. The diffusion bonding comprises solid state diffusion between the first mass and the second mass. A predominate portion of the developed grains in the second material have a maximum dimension of less than 100 microns. The invention also encompasses methods of forming a physical vapor deposition target bonded to a backing plate.

摘要： There is provided a surface treatment method of metal that can endow the surface of a metallic material with strong bonding force in a simple process regardless of the profile and the substance of the metallic material as well as a metallic material obtained by such a method. The method comprises a first step of conducting a chemical etching process accompanied by formation of a film coat on the metal surface and a second step of chemically removing the film coat formed on the metal surface in the first step. If necessary, it may further comprise a third step of forming a thin layer on the metal surface after the second step.

摘要： The process for removing a soap-contaminated conversion layer remaining on a metal workpiece after cold-forming with an aqueous acidic cleaning composition containing water, a surfactant such as an alkyl amine ethoxylate and nitric acid, phosphoric acid and/or amidosulphonic acid includes immersing the contaminated metal workpiece in the aqueous acidic cleaning composition at a temperature above 60.degree. C. until it has a clean bright surface and a fatty acid formed by reaction of the soap in the conversion layer is dispersed in the cleaning composition and then subsequently separating the metal workpiece from the cleaning solution and, after the separating, cooling the recovered aqueous acidic cleaning composition to a temperature below 55.degree. C. until a fatty acid layer including the fatty acid is separated from the aqueous acidic cleaning composition. The fatty acid layer is removed from the aqueous acidic cleaning composition to form a reusable aqueous acidic cleaning composition and then other metal workpieces are cleaned with the reusable aqueous acidic cleaning composition.
