Evaluation of the lubricating power of sweet almond oil without additives

The lubricity of sweet almond oil (Prunus amygdalus var. Dulcis) was evaluated through Anti Wear (AW) properties and Extreme Pressure (EP) performance in a four-ball tribometer. The results were compared to those obtained with two mineral oils of contrasting viscosity, namely technical white mineral...

Los resultados obtenidos, se compararon con el comportamiento de dos aceites minerales de diferente viscosidad, blanco técnico y plastificante delta 360, sin aditivos. Se determinó que el aceite de almendras dulces posee mayor poder lubricante con respecto a los aceites minerales. Las esferas lubricadas con aceite de almendras presentaron menor diámetro promedio de la huella de desgaste y menor coeficiente de fricción. Además, el aceite de almendras dulces presentó mejor desempeño en condiciones de extrema presión, mostrando un punto de soldadura mayor que los aceites minerales. Finalmente, mediante el análisis por espectroscopia FT-IR, se determinó que en las condiciones en las que se realizaron los ensayos el aceite de almendras no se oxida.application/pdfspaUniversidad Nacional de Colombia - Sede Medellín - Facultad de Minashttps://revistas.unal.edu.co/index.php/dyna/article/view/68033Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaDelgado-Tobón, Arnoldo Emilio and Aperador-Chaparro, William Arnulfo and García Cáceres, Rafael Guillermo (2018) Evaluation of the lubricating power of sweet almond oil without additives.
