APPLICATION OF SINTERED BIOMATERIALS MADE OF THE 316L STEEL IN FRICTION COUPLES OF ARTIFICIAL HIP JOINTS
Journal Title: Tribologia - Year 2010, Vol 229, Issue 1
Abstract
One of the most common among the biotribological issues is elongation of joint endoprosthesis durability. Necessity to ensure favourable friction parameters along with the implants biocompatibility requirements forces search for new solutions. The new conception of tribological system of hip joint endoprosthese, based on the idea of porous selflubricating bearing, was presented in this work. Hip joint cup with porous layer made of porous sintered 316L steel should ensure low friction coefficient as well as low wear of working elements. Research were undertaken on hip joint friction simulator. Similar tests were taken for traditional polyethylene cup for comparison. Wear assessment were led in accordance with ISO 14242-2. Experimental research confirmed legitimacy of the conception of porous hip joint bearing.<br/><br/>
