Laser Cladding Functionally Graded Composition of Molybdenum Disilicide and Co-Based Alloy

Abstract:

An approach for fabricating functionally graded specimens of Co-based alloy and molybdenum disilicide (MoSi₂) compositions via Selective Laser Cladding (SLD) is presented. The focus aimed at using the functionally graded material (FGM) concept to gradually grade powdered compositions of MoSi₂ within a base material of Co-based alloy. A high power CO₂ laser was used to process the material compositions to a high density with gradual but discrete changes between layered compositions. The graded specimens initially consisted of 100% Co-based alloy with subsequent layers containing increased volume compositions of MoSi₂ (0-80wt.%). Specimens were examined for porosity, phase composition and microstructure. It was found that crack sensitivity of layer can be reduced by adding Co-based alloy into the pure MoSi₂ powder.
