Abstract
In this study of laser power on deposited of Ti64l4V/W was
investigated. The energy flow rates were varied while every
single other parameter were kept at a steady. The evolving
microstructure and the hardness of the composites were
studied and reported in this study. The study established that
the laser metal deposition process is suitable for producing
acceptable bonding between a deposited zone and a substrate
zone. The hardness values of the deposits varied from 377HV
to 719HV. The laser power directly influences the hardness
and the microstructure. Scanning electron microscopy (SEM)
was utilised to characterise the microstructure of the composite
layer formed on the surface of the Ti6Al4V substrate. The
microstructure of all the composite layers delivered by the
LMD procedure has upgraded properties in connection to that
of the Ti64l4V substrate.
