“…Improved properties were linked not only to the presence of surviving CrB 2 particles but also to the secondary precipitation of finely dispersed chromium borides (CrB and Cr 2 B) and iron borides (Fe 2 B) following the partial dissolution of the initial CrB 2 particles. Li et al [57] added CeO 2 nanopowder in laser-cladded FeCrBSi/NbC composites: CeO 2 nanoparticles acted as heterogeneous nuclei, favouring higher solidification rates and enhancing the in situ synthesis of finely dispersed NbC (see also Section 4.2).…”

“…Fe/TiC composites have been produced by LC, resulting in a significant increase in the hardness of the composite coating when compared to the substrate [37,91]. Finely dispersed NbC were obtained from blended elemental powders during the LC of FeCrBSi matrix composites, with the addition of CeO 2 nanoparticles acting as heterogeneous nuclei enhancing the precipitation of NbC [57]. Song et al [85] took advantage of the dissolution and reprecipitation of SiC micron-sized particles in pure Fe during SLM to produce Fe/SiC bulk nanocomposites.…”

Since current trends in the transportation, energy or mechanical industries impose increasingly demanding service conditions for metallic parts, metal matrix composites MMCs are the object of a growing interest. Powder-based laser additive manufacturing, which allows making parts with complex shapes, appears particularly adapted for the production of MMCs. This paper reviews the current state-of-the-art in the production of MMCs by additive processes, with the aim of assessing the potentials and difficulties offered by these techniques. Two main processing routes are envisaged, i.e. the processing of ex situ composites in which the reinforcing phase as a powder often of ceramic particles is directly mixed with the powder of the matrix alloy, and both powders are simultaneously processed by the laser."lternatively, the reinforcing phase can be produced in situ by a chemical reaction during the fabrication of the composite. For both processing routes, a careful control is needed to overcome challenges brought, e.g. by the behaviour of the reinforcement particles in the laser beam, by changes in laser absorptivity or by the dissolution of the reinforcing particles in the molten metal, in order to produce MMCs with enhanced usage properties.

“…Hao et al [7] investigated the effects of rare earth oxide on the hardfacing metal microstructure of medium carbon steel and pointed out that the microstructure was refined at first and then coarsened with the increase in rare earth oxide addition. In situ Fe-NbC composite laser cladding layer with different CeO 2 addition was produced in die steel by Li et al [8], and it is shown that CeO 2 plays important roles in reducing microporosities, refining grains and improving the precipitation of NbC. Golmakaniyoon et al [9] found that the creep http://dx.doi.org/10.1016/j.apsusc.2014.09.195 0169-4332/© 2014 Elsevier B.V. All rights reserved.…”

“…powders have been used as laser cladding materials in virtue of the characteristics of low melting point and good wettability [ 13 ]. Moreover, previous investigations indicated that the composite materials composed of self-fluxing alloy powders and hard ceramic particles can fabricate coatings with a better microstructure and better mechanical properties [ 14 , 15 , 16 ]. As the solid solution of TiC and TiN, Ti(C,N) ceramics exhibit superior properties of high hardness and superb wear resistance and are often regarded as ideal reinforced phases.…”

Using Ni60 alloy, C, TiN and Mo mixed powders as the precursor materials, in situ synthesized Ti(C,N) particles reinforcing Ni-based composite coatings are produced on Ti6Al4V alloys by laser cladding. Phase constituents, microstructures and wear properties of the composite coatings with 0 wt % Mo, 4 wt % Mo and 8 wt % Mo additions are studied comparatively. Results indicate that Ti(C,N) is formed by the in situ metallurgical reaction, the (Ti,Mo)(C,N) rim phase surrounding the Ti(C,N) ceramic particle is synthesized with the addition of Mo, and the increase of Mo content is beneficial to improve the wear properties of the cladding coatings. Because of the effect of Mo, the grains are remarkably refined and a unique core-rim structure that is uniformly dispersed in the matrix appears; meanwhile, the composite coatings with Mo addition exhibit high hardness and excellent wear resistance due to the comprehensive action of dispersion strengthening, fine grain strengthening and solid solution strengthening.
