Viscous flow, sliding velocity sweep and transient friction tests were carried out and resulting wear scars in the steel plates were evaluated by means of scanning electron microscopy (SEM). Different frictional responses were found depending on the thickener, especially at high temperature. Excepting for most severe conditions, wear is negligible when using chemically modified chitin and methylcellulose-based greases as lubricants. © 2015 Elsevier Ltd.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 1</style></notes></record></records></xml>
