    Recubrimientos bimodales de WC-co-VC nanoestructurado aplicados por rociado térmico como alternativa del cromo hexavalente para trenes de aterrizaje. by Valladares Hernández, Julio César

    Published 2018
    “…The additions of 5 % of vanadium carbide with 50% of nanostructured particles in the coatings, allowed to reduce the friction coefficient up to 27% compared with the coating without VC additions and nor nanostructured particles, so it was shown that the refinement of the microstructure to the nanometric dimensions and the additions of VC favorably influence the wear resistance. The statistical analysis of the experimental matrix allowed to establish the concentration of 1.36% of VC and 50% of nanostructured particles to obtain coatings with the desired mechanical properties.…”
