Energy redistribution during CO2 laser cladding

, 2001
This paper examines the factors that effect the efficiency of the CO sub 2 -laser powder cladding process. By theoretical calculation and experimental work it has been possible to identify how much of the original laser energy contributes to the cladding

Laser cladding with powder

This thesis is directed to laser cladding with powder and a CO2 laser as heat source. The laser beam intensity profile turned out to be an important pa6 Summary rameter in laser cladding. A numerical model was developed that allows the prediction of the surface temperature distribution that is attained with an arbitrarily shaped intensity profile ...

Study for Laser Cladding of Ni60A on Copper Substrate by Laser

, 2008
The Ni60A powder was clad on the copper by the laser through coaxial power feeding. The hardness and erosion resistance of the substrate and the cladding layer were measured and made contrasts. The morphology and the microstructures of the cladding layer
