    Contact fatigue behavior of α-Al PROOF 2 O -Ti(C,N) CVD coated WC-Co under dry and wet conditions
    (2020-11-07) Sosa, D.A.; Collado Ciprés, Verónica; García, José Luis; Dalibón Bähler, Eugenia Laura; Escalada, Lisandro; Roa, Joan Josep; Soldera, Flavio; Brühl, Sonia Patricia; Llanes, L.; Simison, Silvia
    The response to cycling contact fatigue load of a WC-6%Co carbide coated with a Ti(C,N)/α-Al2O3 CVD multilayer was investigated in dry and wet conditions.

    Corrosion and properties of low temperature plasma carburized austenitic stainless steel
    (2018-09-28) Gasco, Ana Sofía; Brühl, Sonia Patricia; Soldera, Flavio; Aristizabal, Katherine; Marcos, Gregory; Noel, Cedric; Czerwiec, Thierry; Simison, Silvia
    This work has the aim of develop and characterize the low temperature plasma carburizing of stainless steel AISI 316L of two dierent grades (commercial and medical grades). The process was carried out in an experimental reactor in UL-Nancy, France, designed for low-pressure plasma treatments.

    Corrosion and wear properties of plasma nitrided 316L stainless steel
    (2018-09-28) Brühl, Sonia Patricia; Simison, Silvia; Escalada, Lisandro; Manova, Darina; Maendl, Stephan; Vaca, Laura Silvia; Soldera, Flavio; Guitar, María Agustina
    Since 2010, in the frame of the European SUMA2 project and the binational project, the University of Saarland (Saarbrucken, Germany), the Leibniz Institute (Leipzig, Germany), INTEMA (Mar del Plata, Argentina) and the UTN-FRCU (Concepción del Uruguay, Argentina) have worked in collaboration to developed and characterize the successful nitriding of austenitic stainless steels by dierent plasma assisted techniques such as Plasma Immersion Ion Implantation (PI3), DC Pulsed Plasma Nitriding and Low Energy Ion Implantation (LEII) XRD have been performed in order to characterize the structure of the surface layers.
