“Wear Behavior of Micro-Textured Metal Component Surfaces Used in Artificial Joints”
Faculty Mentor: Dr. L.D. Tim Topoleski
Expected Graduation Date: December 2009
The purpose of the research is to determine the wear behavior of micro-textured carbide (brain coral) surfaces under conditions relevant to artificial joints. The hypothesis to be tested is that the use of modified micro-textured surfaces on metal surface in artificial joints will result in less wear of the surfaces compared to the non-textured surfaces, or surfaces that have not been modified. The motivation behind the research is that the micro-textured carbide surface layer is more wear-resistant than a non-coated alloy. Using micro-textured surfaces can reduce wear in artificial joints which is the prime factor for prosthesis loosening and initiating osteolysis – the destruction of bone surrounding the prosthesis. Examining the wear behavior of the surfaces can be a vital factor in developing breakthroughs leading to ‘ideal’ bio-materials and failure-free artificial joints.
