应用
Sputtering is a process whereby atoms are ejected from a solid target material due to bombardment of the target by energetic particles. The extreme miniaturization of components in the semiconductor and electronics industry requires high purity sputtering targets for thin film deposition.

Conventional porous-coated joint prostheses used in hip and knee reconstruction have demonstrated good clinical results, however, these implants possess some inherent shortcomings such as low volumetric porosity, suboptimal frictional characteristics, and higher modulus of elasticity relative to that of bone.
