“…The strong influence of the surface finish on the tribological behaviour observed for the self-lubricating composites [141] led the group to focus on surface finish, in particular resulting from turning [187,188], post-sintering sizing [189], and cryogenic hardening [190]. Also noteworthy are some activities associated with fundamental aspects of tribomaterials, such as a thermodynamic approach to sintering [191], the thermal stability of MoS 2 in powder injection moulding [192], physicochemical characterization of tribolayers by micro-Raman and glow-discharge optical emission spectroscopy (GDOES) [193], and finally, bio tribological aspects affecting the development of dispersions to mitigate the oropharyngeal dysphagia [194].…”
