An ever increasing mobility and a shortage of resources lead to restrictive politically driven limits for fuel consumption as well as an increasing demand of customers for efficient vehicles. Though electrification of cars proceeds, combustion engines will play an important role for conventional and hybrid concepts within next decades.

Sliding tribological behavior of AlCrN coating
Tribology International, 2008Abstract The sliding tribological behavior of the PVD AlCrN coating against Si3N4 ball have been investigated by using the CETR multi-functional UMT-2 test system under two sliding conditions (bidirectional and unidirectional). Reciprocating sliding tests (bidirectional) were performed under varied normal loads (5, 10 and 20 N) at sliding velocity of

Tribological behavior of PTFE film with nanodiamond
Surface and Coatings Technology, 2004The effect of nanodiamond addition on the tribological behavior of polytetrafluoroethylene (PTFE) film was investigated. Nanodiamond particles produced by detonation method were added up to 4 wt.% to PTFE film to improve the wear resistance and thermal stability.

Study of PTFE composites tribological behavior
Wear, 2012Abstract A comparative analysis of seven PTFE composites is presented showing how properties of PTFE can be improved even if the most attractive characteristic of low friction is lost due to the presence of hard particles in the polymer matrix. How the use of both soft and hard phases in a polymer matrix enhances the self-lubricating and the load ...

Tribological behavior of nanoclay/epoxy composites
Materials Letters, 2007This paper aims to discuss the mechanical performance of nanoclay/epoxy composites (NCs) through micro-hardness and abrasive tests. It was found that the hardness and wear resistance of NCs increased with increasing nanoclay content of up to 4 wt.%. The improvement of mechanical properties of the NCs by increasing nanoclay content is explained by the ...

Tribological and Nanomechanical Behavior of Liquid Wood
Journal of Tribology, 2018During the last decades, there has been an increased interest in the use of lignin-based composites following the ideas of developing green materials for fossil-based raw materials substitution. The biopolymer Arboform is a mixture of lignin, plant fibers, and additives, which is nowadays successfully used in many applications.

Tribological behavior of metal matrix composites
Wear, 1979Abstract : The wear and friction behavior of continuous graphite-fiber-reinforced metal matrix composites was investigated. Composite materials were tested against 4620 steel at 54 m/sec at room temperature in air without lubricant. The graphite fibers studied included rayon-based, pitch-based, and polyacrilonitrile (PAN)-based fibers.

Tribological behavior of vanadium oxicarbide coatings
Surface and Coatings Technology, 1997Abstract Vanadil acetylacetonate (VO(C 5 H 7 O 2 ) 2 ) precursor was used for the chemical vapor deposition of vanadium oxicarbide coatings on substrates made of three grades of steels: AISI 304, AISI 316 and HCM9M. The coated samples were subjected to hardness measurements as well as to ball crater, scratch and pin-on-disk tests in order to observe ...

Microstructure and tribological behavior of polymeric nanocomposites
Industrial Lubrication and Tribology, 2001Nanocomposites represent a new prospective branch in the huge field of polymer materials science and technology. It has been shown that an overall enhancement of properties of polymers can be achieved under certain conditions by the addition of nanoparticles.
