INVESTIGATION OF WEAR BEHAVIORS OF PROSTHETIC MATERIALS ON BALL-DISC EXPERIMENT
Özet
In this study; The abrasion performances of uncoated Ti-6Al-4V and uncoated AISI 316 L stainless steel material were investigated in a ball-disc test apparatus. The experiments were carried out with 100Cr6 balls 10 mm in diameter in dry and sodium hyaluronate media to give a 500 m path under the influence of 7,5 N and 10 N forces at shear rates of 1-1,5-2 m/s. The wear quantities of the test specimens were examined for the ball and disc. As a result, it is observed that Ti-6Al-4V material is more resistant to abrasion than stainless steel material. The erosions in the medium added with sodium hyaluronate are very small compared to the dry medium and the erosion is reduced by 30-35% compared to the dry medium.
