摘要
在电解抛光钛合金(Ti-6A l-4V)植入物的过程中引入功率超声波。分析了功率超声波对电解抛光过程的作用及对抛光效果的影响。通过合理利用功率超声波的能量特性,发挥其对传质过程的强化作用、空化效应,并与电化学抛光的特点相结合,对钛合金植入物进行抛光处理。结果表明,引入功率超声波,不但可以大幅度改善钛合金植入物的表面粗糙度,而且还可以增加其表面氧化膜中Ti的氧化物含量,进一步提高钛合金植入物的生物相容性和耐腐蚀性。
The intensity ultrasonic waves have been introduced in electrochemical polishing of biomedical titanium alloy ( Ti-6Al-4V). The action of intensity ultrasonic waves on electrochemical polishing process and the influences of ultrasonic waves on polishing quality have been analyzed. By effectively utilizing the energy effects of intensity ultrasonic waves, exerting its intensity action and cavitation effects on mass-transfer, and by organically combining the features of intensity ultrasonic waves with electrochemical polishing during the process of polishing for biomedical titanium alloy implants, better results have been obtained: the surface roughness of titanium alloy implants can be improved greatly, the content of titanium oxide in oxide films may be increased, and the biocompatibility and corrosion resistance of titanium implants may also be promoted.
