Estimation of Surface Topography and Wear Loss of Laser Metal-Deposited Ti6Al4V and Cu

The atomic force microscopy (AFM) analysis is a process that involves the detailed analyses of the surface of a three-dimensional sample piece. A good image is always generated on such a sample once the settings are implemented correctly. And as such, the amplitude set point plays a vital role in achieving a better image. This paper presents the evolving microstructures and the surface topographies of the laser-deposited Ti6Al4V/Cu alloys. The formation and the output of the microstructure depend on the laser processing parameters employed. The migration of the β-phase has been impeded during solidification due to the low strain hardening effect posed by the α-Ti lamella. A correlation between wear loss and surface roughness has been established among the laser-deposited samples.
