Surface modification of Ti-6Al-4V alloy was done by developing HA cladding using 400 W fiber laser. A detailed microstructural analysis was carried out by using an optical profilometer, field emission scanning electron microscopy (FESEM), and Energy-dispersive X-ray spectroscopy (EDS). The wettability analysis was performed using Hank’s solution (pH 7.4). The microstructure characterization revealed that surface was rough, porous with presence of few micro-cracks. The Ca, Ti, P, and O elements were distributed uniformly and homogeneously across the HA-cladded surface, according to the EDS mapping. HA-cladded surface showed improvement in wettability properties compared to as-received Ti-6Al-4V alloy.

摘要

Surface modification of Ti-6Al-4V alloy was done by developing HA cladding using 400 W fiber laser. A detailed microstructural analysis was carried out by using an optical profilometer, field emission scanning electron microscopy (FESEM), and Energy-dispersive X-ray spectroscopy (EDS). The wettability analysis was performed using Hank’s solution (pH 7.4). The microstructure characterization revealed that surface was rough, porous with presence of few micro-cracks. The Ca, Ti, P, and O elements were distributed uniformly and homogeneously across the HA-cladded surface, according to the EDS mapping. HA-cladded surface showed improvement in wettability properties compared to as-received Ti-6Al-4V alloy.
