聚醚醚酮人工骨支架钽涂层制备及表征

In order to improve the comprehensive properties of PEEK (polyether-ether-ketone) artificial bone scaffold, in this research the tantalum coating has been prepared on the surface of PEEK artificial bone by DC magnetron sputtering technology in different sputtering conditions. The prepared tantalum coating has been characterized by scanning electron microscope, X-ray diffraction and energy spectrum analysis technology. The results show that different phases of tantalum coating can be prepared by controlling different sputtering pressures and the prepared tantalum coating has high purity and good density.
