Better Than

Aimed at the lack of the cladding materials such as micro or nanopowder, the micro/nanocomposite powders prepared for experiment are feed directly, the key process parameters on the quality of the surface quality and microstructure analysis of the single-layer of laser cladding are studied in detail. Compared to the ordinary laser micro-cladding layer feeding by the micro powder, the cladding layer is more refined, which has more good mechanical properties. The results showed that: using reasonable parameters, the microstructure and macro-morphology of cladding layer with micro-nanocomposite powders feed directly are better than of micron powders.

Three Phases

The experiment of laser cladding on the surface of Cr12 mold steel was made. Ni-coated nano-Al2O3 particles powder was used as cladding material. The microstructure and hardness of laser cladding layer were tested. The research showed that the compact cladding layer without crack, gas hole and other defects could be made by laser cladding. The cladding layer was made up of three phases, Fe-Ni solid solution, Fe-Cr solid solution and nano-Al2O3 particle. nano-Al2O3 particles enhanced the inhomogeneous nucleation of Fe-based alloy, refined the crystal grains and strengthened the mechanical properties of cladding layer. The average hardness of cladding zone was 900 HV0.2 which was 2.2 times higher than that of substrate.

There is large use of directionally solidified superalloy blades in aerospace, but the repair of these blades is a real problem. The laser cladding technology is able to implement the repair. The experiments in this paper study the microstructure of laser cladding, analyze the formation mechanism and control method, implement the directional growth of microstructure in multilevel laser cladding layer, and provide a theoretical and experimental basis of laser cladding repair on directionally solidified superalloy blades.
