Study on Technology of Multi-Trace Overlapping and Rapid Prototype by Broad-Beam Laser Cladding

Abstract:

Obvious physical process differences exist between overlapping area and non-overlapping area by broad-beam laser cladding,also the parallel and vertical interface of RP.By comparing the microstructure and performance, the result shows: the microstructure of overlapping area has broken crystal,the size of overlapping area crystal is bigger than the non-overlapping one.Repeated heating makes overlapping area secondary dissolving out and having higher rigidity;Between layer and layer of broad-beam laser cladding RP is metallurgical combination completely,the degree of uniformity of central microstructures performance is good,hardness of the bow shape area between overlapping layer and matrix is greatly increased.
