| Abstract: | Novel Cr-alloyed MoSi2-based nanocomposite coatings were successfully synthesized onto Ti-6Al-4V substrates by a double glow discharge plasma technique. The architecture of the nanocomposite coatings exhibited a hierarchical structure, consisting of equiaxed C40-MoSi2 with a bimodal grain size distribution and strip-shaped Mo5Si3 grains segregated to the boundaries of submicron MoSi2 grains. The results showed that the toughness of the MoSi2-based nanocomposite coatings depended strongly upon their hierarchical structure and the magnitude of compressive residual stresses in the nanocomposite coatings. © 2013 Elsevier B.V.
