Abstract:

Fabrication of functionally graded materials FGMs by laser metal deposition LMD has the potential to offer solutions to key engineering problems over the traditional metalworking techniques. But the issues that need to be addressed while building FGMs are intermixing in the layers and cracking due to the residual stresses. This paper is to present the study of the effect of process parameters laser power and travel speed on the degree of dilution between the substrate or, previous layer and powder material for few metallurgical systems.
