摘要
316L stainless steel and Ni35 self-melt alloy were selected to perform laser multi-layer cladding experiments on the Ni-base superalloy directional solidification substrate. Mechanisms of microstructure formation were investigated. Results show that directional solidification cladding layers of 316L stainless steel with fine crystallography orientation under the processing parameters mentioned in this paper were obtained. While for the nickel-base self-melted alloy Ni35 which is not easy to acquire columnar dendrite tend to appearing equiaxed grains in the cladding layers under similar processing condition.
