An energetical approach to study the structural degradation of traditional and biogenic lubricating greases
(Universidad de Huelva, 2022)En un contacto tribológico, los procesos de fricción conducen a efectos irreversibles asociados al desgaste, que son el resultado de un aporte de energía de fricción al un sistema tribológico. En general, se aplican ... -
Experimental Study on the Expended Energy on Structural Degradation of Lubricating Greases
Ahme, Leif; Kuhn, Erik; Delgado Canto, Miguel Ángel
(Springer, 2022)
One of the keystones of tribological studies is the energetical approach to the lubrication process. In the particular case of lubricating greases, part of the lubrication process's energy dissipates due to a shear-induced ... -
Influence of Base Oil Polarity on the Transient Shear Flow of Biodegradable Lubricating Greases
Fiedler, Martin; Sánchez Martínez, Rubén; Valencia Barragán, Concepción; Leopold, Claudia S.; Kuhn, Erik; Franco Gómez, José María (MDPI, 2015)
The scope of this study is to elucidate the physical mechanisms influencing the transient flow behavior of lubricating greases based on biogenic oleochemicals from a polarity point of view. This includes the mutually ... -
Tribological and Rheological Characterization of New Completely Biogenic Lubricating Greases : A Comparative Experimental Investigation
Acar, Nazli; Kuhn, Erik; Franco Gómez, José María (MDPI, 2018)
Against the background of raw material shortage and the ever-expanding environmental consciousness, the use of biodegradable greases becomes more and more important. The aim of this experimental work is to investigate ... -
Tribological and rheological investigation of the applicability of biogenic lubricating greases as separating medium in highly stressed friction systems
(Universidad de Huelva, 2014)Actualmente existe una gran demanda de grasas lubricantes medioambientalmente amigables que sólo puede ser satisfecha parcialmente. El propósito de este trabajo es investigar, fundamentalmente, el efecto que los principales ... -
Tribological Investigation on the Friction and Wear Behaviors of Biogenic Lubricating Greases in Steel–Steel Contact
Acar, Nazli; Franco Gómez, José María; Kuhn, Erik; Seabra, Jorge; Gonçalves, David (MDPI, 2020-02)
The applications of biogenic lubricating greases to machine elements play important roles in the reduction of friction energy and minimizing wear in a tribological contact, as well as the prevention of environmental ...
