    Comportamiento mecánico de un recubrimiento DLC depositado sobre acero inoxidable martensítico previamente nitrurado
    (2013-05-07) Dalibón Bähler, Eugenia Laura; Charadía, Raúl; Cabo, Amado; Trava-Airoldi, Vladimir Jesús; Brühl, Sonia Patricia
    En este trabajo se estudió el comportamiento tribológico de un film de DLC que fue depositado sobre acero inoxidable martensítico AISI 420 nitrurado, con dos terminaciones superficiales diferentes, previas a la nitruración iónica, analizando los resultados en función del acabado superficial.

    Influence of the silicon interlayer deposition process in the adhesion of the DLC coatings deposited on nitrided martensitic stainless steel
    (2017-08-25) Dalibón Bähler, Eugenia Laura; Lugo González, Dubrazkha Carolina; Ramírez Ramos, Marco Antonio; Trava-Airoldi, Vladimir Jesús; Brühl, Sonia Patricia
    The DLC coatings are characterized by good wear resistance, low friction coefficient and chemical inertness [1]. However, they have adhesion problems when they are deposited on metallic substrates. For this reason, a thin interlayer of different materials, such as silicon, is deposited previous to the coating in order to improve the adhesion. There are a few studies about the influence of the conditions of the silicon interlayer deposition on adhesion or properties of the coatings [2,3]. In this work, the adhesion of DLC coatings deposited on nitrided and non-nitrided martensitic stainless steel, modifying the silicon interlayer bias potential deposition, is studied.

    Estudio del comportamiento mecánico de recubrimientos DLC multicapa depositados sobre el acero inoxidable martensítico nitrurado
    (2019-10-02) Dalibón Bähler, Eugenia Laura; Brühl, Sonia Patricia; Cabo, Amado; Pecina, Jorge Nahuel; Trava-Airoldi, Vladimir Jesús; Caballero, Mario Alberto
    El acero inoxidable martensítico AISI 420 posee diferentes aplicaciones en la industria donde se requiere buena resistencia al desgaste y a la corrosión. Para mejorar sus propiedades superficiales, algunos tratamientos pueden ser aplicados como recubrimientos “Diamond Like Carbon” (DLC) que se caracterizan por su buena resistencia al desgaste, bajo coeficiente de fricción y ser químicamente inertes. Sin embargo presentan problemas de adhesión cuando son depositados sobre sustratos metálicos entonces un pretratamiento como la nitruración asistida por plasma puede resultar conveniente.
