Variable Composition Laser Cladding of Copper Alloys
It as been shown that laser cladding can be achieved by blowing powder into a laser generated meltpool — resulting in low dilution homogeneous tracks. By overlapping these tracks it is possible to clad an entire surface. 25% Pb-bronze, clad onto EN 3 mild steel, was chosen as a first model system in order to demonstrate that it is possible to clad an alloy whose constituents have a large difference in melting points. The effect of process parameters (such as powder feed rate) was investigated. Variable composition single track clads were then produced. This was achieved by progressively adding Ni powder during cladding. The microstructure and properties of the resultant variable composition tracks was investigated.
