Fabrication of nanoparticulate reinforced metal matrix composites by laser cladding

The nanoparticulate reinforced metal matrix composites (nPRMMCs) can further improve the ductility and fracture toughness of conventional microscale PRMMCs. The uniform dispersion of nanosized hard particles in the matrix is vital due to their strong tendency to agglomerate. This paper summarizes the state-of-the-art fabrication process of nPRMMCs by laser cladding via both ex-situ route and in-situ route. Concerns have been focused on the uniform dispersion of nanoparticles and their interface bonding with the matrix. The current challenges and future developments are discussed. This summarization will be helpful for the further research on the fabrication and applications of nPRMMCs. © 2014 Laser Institute of America.
