Cheap nano-clay additive as a lubricating enhancer

Janusz Rebis, Jaroslaw Frydrych, Jakub Skibinski, Krzysztof Rozniatowski


Cheap nano-clay (montmorillonite) was taken into consideration in this study as an additive to mineral oil to improve its lubricating
properties. Mineral oils form the basis of speciality lubricants for food processing technology due to their biodegradability.
In contrast to synthetic oils they are also less harmful. Literature indicates that nano-particles additives have a huge impact
on lubricating properties. In this work wear scare diameter (WSD), friction coefficient and film thickness were studied.
High frequency reciprocating rig (HFRR) was used to measure the said lubricating properties of prepared mixtures. Authors
performed roughness measurements on sample plates after HFRR tests to study the relationship between WSD and Ra.
