Investigation on surface integrity of Co-Cr L605 alloy in photochemical machining

This investigation is focused on the surface integrity of Co-Cr L605 using photochemical machining (PCM). The study focuses mainly on the effects of different manufacturing processes, such as forging, wire-EDM, and rolling, on the metallurgical parameters of Co-Cr L605 in PCM. Results were obtained for residual stresses, grain size, local grain misorientation, and interplanar distances. Effects on the etch rate and surface roughness were studied, and found to be maximum for forging, while they were lower for rolling. An overall study was conducted to correlate PCM process parameters with bio-functional aspects of the Co-Cr L605 alloy.
