The surface topography in machining of medical metallic materials: A review

摘要

Biomedical materials are materials that can be implanted in an organism or combined with biological tissue. They are used for the diagnosis, treatment, and replacement of tissues or organs, and enhance their functions. With high strength, good toughness and bending fatigue strength, excellent processing performance which can not be replaced by other medical materials, biological medical metallic materials, such as stainless steel, cobalt based alloy, titanium and titanium alloys and noble metal are widely used in medical field. The surface topography has a great influence on the function of the parts, especially for the wear, vibration, noise, corrosion resistance of the friction surface. And the surface morphology of medical metal is very important in the influence of its corrosion resistance.
