    摘要: A method for manufacturing a sputtering target includes the steps of: providing a highly pure matrix material containing a magnetic metal, and a highly pure precious metal ingot material; cleaning the surfaces of the matrix material and the precious metal ingot; vacuum melting the matrix material and the precious metal ingot to obtain a molten alloy; pouring the molten alloy in a mold having a cooling system while maintaining a surface of the molten alloy at a molten state by arc heating until the pouring is finished, thereby forming the molten alloy into a cast blank; hot working the cast blank; and annealing the cast blank after the hot working.

    摘要: A method for manufacturing a cobalt (Co) alloy-based ceramic composite sputtering target is provided. A cobalt ingot and a chromium (Cr) ingot are melted in vacuum and then nebulized to form a cobalt-chromium (CoCr) alloy powder. Additionally, a ceramic powder and a platinum powder are wetly mixed to form a platinum-ceramic (Pt-ceramic) slurry, in which the ceramic powder is applied onto the platinum powder's surface uniformly. Next, the CoCr alloy powder and the Pt-ceramic slurry are wetly mixed to form a CoCrPt-ceramic slurry. Thereafter, the CoCrPt-ceramic slurry is dried, molded and compressed to form the cobalt alloy-based ceramic composite sputtering target. The resulted cobalt alloy-based ceramic composite sputtering target, which has a fine and dense structure, uniform composition and lower magnetic permeability, is beneficial to a magnetron sputter deposition process, as well as a film sputtering process used in the magnetic recording industry.
