| Abstract: |
| The interface problem between the extra reinforced phase and the matrix of the ceramic particle reinforced metal matrix composite coating by laser cladding was proposed, and average measures to settle this problem were discussed. It was pointed that the combination of laser cladding and in-situ synthesis technique will resolve the interface problem well. Advances in laser cladding in-situ synthesized composite coating technology were reviewed, including insitu materials reaction system, the reaction mechanism analysis, the improvement on microstructure and performance of composite coatings such as Fe based, Ni based etc. Finally, from two angles of microscopic reaction mechanism and macroscopic practical application, the further research directions were put forward: the complement and verification between in-situ synthesis tests and thermodynamic theory, and the application of computer numerical value imitation technology. |
