Laser deposition of Hydroxyapatite, HAp biomaterial preplaced by spray coating on the coupons made of electron beam melted Ti-6Al-4V is investigated using two types of high power diode laser systems. A 2 kW, continuous wave, top hat profile, rectangular beam, High Power Direct Diode laser (HPDL) is used to compare with a 1kW power, Gaussian profile, circular beam, Fiber Coupled Diode Laser (FCDL) on the effect and efficiency of cladding, its composition and homogeneity. Evolution of microstructure and microhardness of melt and heat affected zone formed during HAp cladding of Ti6Al4V alloy are evaluated.Laser deposition of Hydroxyapatite, HAp biomaterial preplaced by spray coating on the coupons made of electron beam melted Ti-6Al-4V is investigated using two types of high power diode laser systems.
