The monotectic alloy of Pb and Cu poses particular problems in laser cladding due to the separation of the alloy constituents with widely different melting points. This system was clad by laser and the results for a variety of operating conditions are illustrated.
The effects of process parameters on Pb segregation, Fe inclusions from the substrate and porosity are examined and described with reference to the solidification mechanism.
By varying the composition of the powder feed into the laser generated melt pool patterned claddings were produced. The metallurgy of such clads is discussed.
