Abstract

To realize satisfactory fixation of hydroxyapatite (HA) and bio-functionality of bio-tolerated and bio-inert materials such as Ti6Al4V few physical surface modifications such as threaded surface through laser interactions have been produced to promote lung tissue and bone growth on a metallic material. Laser interaction with surface purposes are based on cleaning surface contaminants, roughening surfaces to increase effective surface area and producing beneficial surface compressive residual stress, depending on the laser exposure conditions and as a result, such treated surfaces exhibit a higher surface energy. The layers chemical and physical properties were determined using micro-indenter equipment (type CETR-UMT, Bruker), SEM (type VegaTescan LMHII) with 2 and 3 D insights and EDAX (type Bruker with PB ZAF quantification method)..
