Novell surface structure on metals with improved properties for enhanced mechanical interlocking with bone.
Abstract
For heavy load-bearing implants, mainly metallic materials are used, because they offer the necessary mechanical properties and workability to manufacture designs for a direkt bony anchorage. However, there is growing concern about long-term corrosions and fatigue restistance and the biological consequences of released constituents. High frequency fatigue tests are performed at the Institute of Physics at the BOKU in Vienna by measuring the S-N (or Wöhler) curves. As the life time of materials under cyclic loading depends on their surface conditions, the specifically developed surface structures are compared to polished specimen surfaces. Besides these experiments in air, also environmental influences during mechanical stressing, i.e. corrosion fatigue are investigated.
