    Wear resistance of thermal spray WC-Co-VC nanostructured coatings por Cabral Miramontes, José Ángel, Gaona Tiburcio, Citlalli, Velasco Tellez, Abraham, Poblano Salas, Carlos, Almeraya Calderón, Facundo

    Publicado 2016
    “…Additionally, VC was added to the bimodal mixture and it presented the best characteristics. The combination of VC additions and a bimodal WC particle size distribution in the WC-Co coatings proved successful in increasing their mechanical properties, which permitted the coatings processed in this work to show better mechanical properties than those reported in the literature for coatings having exclusively a bimodal WC particles size distribution or those only doped with VC additions. …”

    Failure analysis of the fasten system of wheels used in mining pickup trucks por Artigas, Alfredo, Monsalve G., Alberto, Colás Ortíz, Rafael, Garza Montes de Oca, Nelson Federico

    Publicado 2017
    “…By means of scanning electron microscopy, optical microscopy analyses and hardness tests, it was found that failure of the fasten system is characterised by a series of synergetic steps that include, the plastic deformation of the lug nuts caused by deficient tightening practices, fatigue and plastic deformation of the bolts. When combined, these phenomena leaded to the formation of cracks that propagated in the radial direction of these elements. …”
