Abstract

Decisive requirement for the long-term stability of the artificial joint is to minimize the release of debris particles. The wear/debris induced osteolysis and aseptic loosening are the result of failure of metal-on-metal joint implants. Severe plastic deformation (SPD) processes have been used to adapt the surface integrity properties by generating ultrafine or even nano-sized grains and grain size gradients in the surface region of work materials. These fine grained materials often show enhanced surface integrity properties such as wear resistance, corrosion resistance, fatigue life and improved functional performance compared with their predictable coarse grained counterparts. Metal-on metal bearings have a long history in total hip replacement. The experimental trials are planned according to Taguchi DOE in dry as well as in wet machining environments. It is shown that depth of cut is statistically significant on cutting force components and having dominating effect on radial and feed forces during precision turning of Co-Cr-Mo bio-implant alloy in dry machining environment. However, depth of cut and tool material both are statistically significant and show substantial effect on feed, radial and cutting forces in wet machining environment respectively. It is found that CBN insert gives better results in magnitudes of all cutting force components w.r.t. surface integrity therefore it is preferable to machine Co-Cr-Mo bio-implant alloy using CBN insert than any other tool materials.
