| Abstract: | The effects of calcification treatments under the impulse supply on the properties of apatite layer fabricated on NiTi shape memory alloys are investigated. Impulse current is an important parameter for the film forming law of apatite layer. This article has analyzed the effects of impulse parameters, after that obtained the applicable impulse parameters. The results indicated that pulse current was beneficial to deposition of apatite layer, and remarkably enhanced the density and purity of hydroxyapatite layer. |
