Abstract
The study of laser power on deposited of Ti64l4V/W was
investigated. The laser metal deposition technique has proven
to be a process that is sustainable. The microstructure and
microhardness properties of a Tungsten powder strengthened
composite coating produced via the laser metal deposition
process were investigated in this study. Laser metal deposition
was completed utilizing laser power of 800W, 900W, 1100W,
1000Wand 1200W. Scanning electron microscopy (SEM) and
microhardness machine were used to characterise the
microstructure and hardness of the composite layer formed on
the surface of the Ti6Al4V substrate. The microstructures of
all the composite layers produced by the Laser Metal
Deposition process were enhanced relative to those of the
Ti64l4V substrate.
