Abstract
Generation of controlled UHMWPE wear particle size and shape has been achieved by texturing the steel surface through controlled abrasion. These particles were tested for bioactivity and elongated particles were found to have a higher bio-response than spherical particles. This finding has significant implaications for future materials development and joint designs. To further refine the size and shape control, silicon microfabrication techniques were used to produce uniform surface features of a particular dimensions. This paper describes the relationship between size and shape of the surface features and wear particle size and shape. Diamond scratched stainless steel plate and silicon micro-fabricated surface features were studied. The length of cutting edge of surface feature was found to limit the major axis length of the particles.Citation
