Selective laser melting (SLM) technology is useful for the fabrication of porous titanium implants with complex shapes and structures. The materials fabricated by SLM characteristically have a very rough surface (average surface roughness, Ra=24.58 µm). In this study, we evaluated morphologically and biochemically the specific effects of this very rough surface and the additional effects of a b...
In the manufacturing process beam pipes acquire a structure on their inner walls with a roughness depth in the order of typically 0.5 μm rms. This surface structure is polarised by the beam and can be interpreted as an artificial dielectric. The thin dielectric layer model shows, that for rough tubes there is exactly one synchronous mode, the so called “rough tube mode” (normally in the THz reg...
BACKGROUND AND PURPOSE Under physiological loads, debonded cemented femoral stems have been shown to move within their cement mantle and generate a fluid pump that may facilitate peri-prosthetic osteolysis by pressurizing fluid and circulating wear debris. The long-term physiological loading of rough and polished tapered stems in vitro has shown differences in performance, with greater interfac...
