Abstract
The current paper presents the results of recent studies of the effects of laser processing parameters on the microstructure and surface topology of laser grooved Ti-6Al-4V surfaces used for biomedical applications. Laser micro-grooves are produced using a diode pumped solid state (DPSS) lasers at 355 nm and different pulse repetition frequencies (PRF). The underlying microstructures and surface topologies of the grooves are then characterized using scanning electron microscopy (SEM). Laser/material interaction mechanisms are discussed and optimal laser processing parameters are developed. The implications of the microstructural and topological features are then assessed for cell/surface interactions and adhesion.
