    摘要: A method of making a composite orifice having a tungsten core which is diffusion bonded to a molybdenum shell. Tungsten and molybdenum powders in contact with each other in a mold are isostatically pressed to form a pressed bonded composite part. The pressed, unsintered tungsten core portion of the part is then machined to the desired dimensions. The pressed composite part is then sintered to form a diffusion bonded composite orifice. The pressed and sintered molybdenum shell portion of the orifice may then be machined to the desired dimensions.
