Investigation of wear behavior of Ti-6Al-4V and AISI 316 L biomaterials with ball on disc test device

Abstract

Ti-6Al-4V material is generally used in biomaterial applications. However, this material is difficult tosupply and an expensive material. Instead of Ti-6Al-4V material; It is investigated whether the use of316 L material as an alternative is easier and more economical. In this study, Ti-6Al-4V and AISI 316 Ltest specimens made of the material subjected to the test under the same conditions wear performancewere investigated using the ball on disc experimental setup. The experiments were carried out in threereplicates in a dry and liquid medium. As a result, in the experiments; AISI 316 L samples are coatedwith PVD method compared to other samples in wear rates and abrasive wear marks on the surface ofthe samples were found to decrease. In studies using sodium hyaluronate fluid, it was found that the rateof abrasion and wear traces decreased compared to the dry environment. It was determined that 316 Lsamples coated with PVD method showed better wear performance compared to uncoated Ti-6Al-4Vmaterial. Considering the density differences of Ti6Al4V and 316L materials, 316L can be used insteadof Ti6Al4V material.
