An ad-hoc fretting wear tribotester design for thin steel wires
Llavori, Inigo; Zabala, Alaitz; Tato, Wilson; Aginagalde, Andrea; Gómez Rodríguez, Xabier (EDP Sciences, 2018)Steel wire ropes experience fretting wear damage when the rope runs over a sheave promoting an oscillatory motion between the wires. Consequently, wear scars appear between the contacting wires leading to an ... -
Ball-on-flat linear reciprocating tests: Critical assessment of wear volume determination methods and suggested improvements for ASTM D7755 standard
Ayerdi, Jon; Aginagalde, Andrea; Llavori, Inigo; Zabala, Alaitz (Elsevier B.V., 2021)This work presents a critical assessment of wear volume determination methods for ball-on-flat linear reciprocating sliding tribological tests. It revealed that the ASTM D7755-11 standard leads to the highest relative ... -
Desarrollo de procesos de hidroconformado de chapa de aleaciones de aluminio a temperaturas moderadas
Aginagalde, Andrea (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2009)This research work is based on two strategic lines at medium and long term: the use of lightweight materials and the development of innovative processes that improve the forming of these materials. In this thesis, within ... -
Development of a novel method to characterize mean surface peak curvature as a signature of tribological performance of dental implant surfaces
Zabala, Alaitz; Aginagalde, Andrea; Llavori, Inigo; Tato, Wilson (IOP Publishing, 2020)The integrity of dental implant surfaces might be compromised during surgical insertion. Wear and topographical modifications can occur during implant insertion, which can potentially have clinical implications. Accordingly, ... -

Impact of surface roughness on the coefficient of friction of polymer-on-polymer contacts for deflection pulley-rope systems in the lift industry
Guinea, Ainhoa; Aginagalde, Andrea; Tato, Wilson; Llavori, Inigo; Zabala, Alaitz (Springer, 2024)The coefficient of friction (CoF) between the deflection pulley and rope in a lift strongly affects the life span of the rope. Although surface roughness is a key factor affecting the metallic pulley–rope CoF, its effect ... -
