Data analysis techniques for the visualization and classification of historical vehicle engines' health status using data-driven solutions

In the field of cultural heritage, the use of non-destructive techniques to determine the state ofconservation of an artifact is of the utmost importance, to avoid damage to the object itself. In this paper, we present a data pipeline and several machine l ...

The Role of Geometrical Parameters in the Lubrication of the Swiss Lever Escapement

Stefano Mischler, Alejandro Roda Buch, Sandra Guadalupe Maldonado

The lubrication regimes of a contact pair escapement-ruby pallet of a Swiss lever escapement have been investigated combining the theory of fluid lubrication with a well-established kinematic and inverse dynamic multibody model. The kinematic analytical re ...

Acoustic emission techniques for the detection of simulated failures in historical vehicles engines

Stefano Mischler, Alejandro Roda Buch, Laura Brambilla

Technical and industrial heritage artefacts are characterized by the presence of mechanisms. The possibility to activate, or reactivate, these mechanisms is an integral part of the cultural values of this kind of patrimony. The artefacts' functionality, ho ...

Laser coating of a Zr-based metallic glass on an aluminum substrate

Roland Logé, Stefano Mischler, Jamasp Jhabvala, Alejandro Roda Buch, Navid Sohrabi

Cladding of a Zr-based metallic glass (MG) on an aluminum substrate was conducted using a layer-wise laser additive manufacturing (AM) method, leading to relative densities higher than 99%. The thickness of the cladding was about 300 μm. The effect of lase ...

Chemo-mechanical effects on the tribocorrosion behavior of titanium/ceramic dental implant pairs in artificial saliva

Anna Neus Igual Muñoz, Alejandro Roda Buch

In this paper, the degradation mechanisms of the ceramic and the metal in Titanium/Zirconia pairs for biomedical applications were analyzed. To do that, an experimental set-up with well-controlled mechanical and chemical conditions was used based on a unid ...
