Patent ID: 8366994

Claim:
A method for manufacturing a cobalt (Co) alloy-based ceramic composite sputtering target, comprising: providing a cobalt-chromium (CoCr) alloy powder, comprising: performing a vacuum melting process for melting a cobalt ingot and a chromium ingot into a CoCr alloy solution; and performing a nebulization process for nebulizing the CoCr alloy solution into a CoCr alloy powder; performing a first wet powder mixing process for allowing a ceramic powder to be uniformly embedded onto a surface of a platinum powder in a solvent, thereby forming a platinum-ceramic (Pt-ceramic) slurry, wherein a purity of the platinum powder is greater than 99.9%, and a hardness of the ceramic powder is greater than a hardness of the platinum powder, and a specific weight of the ceramic powder is smaller than a specific weight of the platinum powder; performing a second wet powder mixing process for uniformly mixing the CoCr alloy powder and the Pt-ceramic slurry, thereby forming a CoCrPt-ceramic slurry; performing a drying process onto the CoCrPt-ceramic slurry to form a CoCrPt-ceramic composite powder; and performing a molding and densification process onto the CoCrPt-ceramic composite powder to form the cobalt alloy-based ceramic composite sputtering target.
