Growing environmental concerns provide motivation to increase the demand and use of environmentally friendly lubricants in many industrial sectors especially regarding the “Cleaner Production” purposes. Biodegradability, good lubricating properties and low production costs are the reasons to consider the plant oils a good alternative as reference to replace the petroleum-based oils that have limited resources. The aim of this work is to show some tribological results on the wear ability performances, regarding steel/steel contacts, of three investigated vegetal basestock oils. Object of investication were the following vegetal oils: Rapeseed Methyl Esther (RME) oil, Hydrotreated Vegetable Oil of Rapeseed (HVO) and raw Jatropha curcas L. oil (JCL). The experimental results are reported in terms of optical surface analysis after the execution of reciprocating tribological tests in presence of the investigated lubricants, under several normal load conditions in order to cover boundary, mixed and EHD lubrication regimes.

Abstract
Growing environmental concerns provide motivation to increase the demand and use of environmentally friendly lubricants in many industrial sectors especially regarding the “Cleaner Production” purposes. Biodegradability, good lubricating properties and low production costs are the reasons to consider the plant oils a good alternative as reference to replace the petroleum-based oils that have limited resources. The aim of this work is to show some tribological results on the wear ability performances, regarding steel/steel contacts, of three investigated vegetal basestock oils. Object of investication were the following vegetal oils: Rapeseed Methyl Esther (RME) oil, Hydrotreated Vegetable Oil of Rapeseed (HVO) and raw Jatropha curcas L. oil (JCL). The experimental results are reported in terms of optical surface analysis after the execution of reciprocating tribological tests in presence of the investigated lubricants, under several normal load conditions in order to cover boundary, mixed and EHD lubrication regimes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
