Abstract

Laser cladding was performed on the ductile cast iron substrate with Ni-base alloy under different process conditions. The cracks were observed. The temperature field and stress field in laser cladding under different process conditions were simulated with ANSYS finite element software. It was found that cracks were influenced by process variables. In certain ranges of laser power and scanning speed, while the other process parameters remain constant, the numbers of cracks increase with laser power increasing. Similarly the number of cracks increases with scanning velocity increasing while the other process parameters remain constant. In comparison with experimental results, the simulation with ANSYS finite element software could help to predict, to some extent, the crack of laser cladded Ni-alloy on ductile cast iron.
