Laser surface modification and more specifically laser surface functionalization is widely being considered as a way to efficiently give the surfaces of innovative high value products added or enhanced surface properties. The technology offers a number of desired advantages over competing technologies, of which: selectivity, relatively high processing speeds and the absence of waste or harmful by-products. Nevertheless, the full range of potential applications and suitable target materials is not yet explored, and some feasibility and implementation challenges remain open-ended concerns. With the limited literature available on laser surface texturing of cobalt chrome alloys, a prevalent implant material, the research presented in this thesis aims to address the suitability of this technology in that context and compare it with the current state-of-the-art in the orthopaedics industry. Furthermore, the transferability of the laser surface texturing process from 2D planar test samples to actual 3D parts will be assessed and the effects of 3D laser processing disturbances on the surface functionality evaluated. Finally, a method for laser processing complex surfaces productively is presented and validated on additively manufactured spherical parts.
