Evaluation of Wear Resistance of Ti Alloys Used for Elements Friction of Knee Endoprosthesis

Abstract

The paper presents research results of resistance to abrasive wear of titanium alloys: Ti6Al4V (commonly used) and Til3Nb13Zr (alloy of new generation) in association with polyethylene (UHMW-PE) predisposed for elements on pair of the knee endoprosthesis. The results were analysed from the point of possibility of an use of new generation titanium alloys as components of such implants. The tests of resistance to abrasive wear of selected kinematic pairs were conducted with the PT-3 tribometer in Ringer’s solution a constant load 2.0 kN, rotational speed of the rotating specimens (Ti13Nb13Zr and Ti6Al4V) 30 rev/min, and test duration 1 or 2 hrs.

Selection of parameters for laser surface texturing of titanium alloys

“…The wear products may cause for e.g. : allergic and inflammation reactions, osteolysis and finally the loosening of the implant [2].…”
