Special Issue "Self-Lubricant"
A special issue of Lubricants (ISSN 2075-4442).
Deadline for manuscript submissions: closed (20 February 2014)
Self-lubricant materials and components have the ability to provide their own lubrication, without the necessity of an external lubricant supply system. Self-lubrication can be achieved in different ways, the oldest one probably being provided by porous systems containing any kind of liquid or solid lubricant in the pores. Well-known examples are sintered bronze filled with oil or graphite. Also widely applied are graphite plugs, coatings and a broad range of polymer (composite)-metal combinations. It is clear that self-lubrication can reduce lubrication, complex lubricant circuits and maintenance costs and can increase productivity. Moreover, in some applications such as biomedical, pharmaceutics and food, the absence of oil is essential. Today ecological advantages, e.g., in offshore conditions, constitute an extra asset.
However, developing new classes of self-lubrication materials with reduced friction and enhanced wear resistance is still a challenging task. Unquestionably, this goal will only be achieved with in depth understanding of the self-lubrication mechanisms, such as transfer film behaviour in combination with creative material and component development. As an example, the principle of porous impregnated materials can considerably be improved by the use of nanopores and nanofillers in the bulk of the material or at its rubbing surface. In this respect, the use of ceramic whiskers on polymer surfaces points towards that direction.
This Special Issue will highlight current status and future advances in self-lubrication, including both material and lubricant aspects, but also surface engineering and design issues. Contributions are solicited both from academic researchers working in the field of tribology and lubrication science and their industrial peers dealing with self-lubricated component design. Exchange of experiences, ideas and research results between university researchers and industrial researchers and developers is envisaged, in order to realize substantial progress in the area of self-lubrication.

Title: Mechanics and physics responsible for the self-lubrication of thin films of granular media

Abstract: Self-lubrication of thin films of granular media (shear bands) is taking place due to multiphysical mechanisms like breakage, wear, evolution of the asperities of the contacts, temperature increase as well as aqueous lubrication due to the chemical release of occluded fluids. In this work we present a review of the mechanics and physics governing these processes. We provide a mathematical framework for modelling self-lubrication of thin films of granular media, treated as a multiphysical instability in the creeping flow regime. Applications of these methods in selected problems of earth sciences (landslides, fault mechanics), combustion physics (chemical reactors) and mechanical engineering (piston engines) are also discussed.
