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 oil and delta 360 plasticizer, neither of them containing additives. Sweet almond oil was found to have greater lubricity than the mineral oils, as the spheres it lubricated had lower average wear track diameter and friction coefficient. In addition, sweet almond oil showed better performance under extreme pressure conditions and a greater weld point than mineral oils. Finally, an FT-IR spectroscopic analysis allowed determining that under the conditions of the current assays almond oil does not oxidize.
En esta investigación se evaluó el poder lubricante del aceite de almendras dulces (Prunus amygdalus var. dulcis) mediante ensayos de desgaste preventivo (AW) y presión extrema (EP) en un tribómetro cuatro bolas. 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.
