Abstract: The review summarises basic tribological concepts for
the stability, sustainability and life of the contact systems,
highlighting the idea that tribological processes are most easily
manipulated through the contact and the third body. If the original
contact pair does not possess a specially inserted intermediate layer
between the two interacting bodies, a secondary protective film forms,
self-organized in the course of the friction processes themselves to
keep the sustainability of the system. The ambition of tribology is to
control friction and wear of the contact: either to find the optimal
material to be placed in contact, or to predict events and phenomena
stimulating the emergence of its own protective layer. A short overview
is done of the ways for obtaining very low friction and wear by applying
the principles of self-organization and green tribology, such as the
selective transfer of material between the contact surfaces and the
superlubricity phenomena.
Keywords: complexity, synergy,
friction, self-organization, selective material transfer,
superlubricity.
