Abstract
Laser Metal Deposition (LMD) is the process of using the laser beam of a nozzle to produce a
melt pool on a metal surface usually the substrate and metal powder is been deposited into it
thereby creating a fusion bond with the substrate to form a new material layer against the force
gravity. A good metal laminate is formed when the wettability between the dropping metal
powder and the substrate adheres. This paper reports the surface roughness of laser deposited
titanium alloy and copper (Ti6Al4V + Cu) using the Atomic Force Microscopy (AFM). This
AFM is employed in order to sense the surface and produce different manipulated images using
the micro-fabricated mechanical tip under a probe cartridge of high resolution. The process
parameters employed during the deposition routine determines the output of the deposit. A
careful attention is given to the laser deposited Ti6Al4V + Cu samples under the AFM probe
because of their single tracked layers with semi-circular pattern of deposition.
