The physical properties of biocompatible titanium surfaces were modified using different techniques of surface treatment. Particularly the measurements of roughness and wetting ability were controlled using six different techniques: polishing, sandblasting, acid attack, laser ablation, ion implantation and nanoparticle deposition. The titanium surface wetting can be modified drastically depending on the used treatment to enhance the hydrophilic or the hydrophobic behaviour of the metallic biocompatible surface. The study demonstrates that a linear relation between roughness and contact angle occurs. Possible applications to permanent or removable prosthesis titanium based are presented and discussed.
采用不同的表面处理技术对生物相容性钛表面的物理性能进行了改性。特别是通过六种不同的技术来控制粗糙度和润湿性的测量：抛光、喷砂、酸蚀、激光烧蚀、离子注入和纳米颗粒沉积。根据所使用的处理方法，钛表面的润湿性会发生显著变化，以增强金属生物相容性表面的亲水性或疏水性。研究表明，粗糙度与接触角之间存在线性关系。还介绍并讨论了基于钛的永久或可摘假体的可能应用。
