- Description: 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.

- Description: 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.
