“…For instance, as shown in Fig. 1, Argibay et al [3] found that a self-lubricating DLC nanocomposite film was in situ tribochemically formed from the ambient hydrocarbons of alcohols and alkanes on the nanocrystalline Pt−Au alloy surface. These films were extremely wear-resistant and underwent no obvious material removal even after 100,000 sliding cycles at a contact pressure of 1.1 GPa.…”

“…These films were extremely wear-resistant and underwent no obvious material removal even after 100,000 sliding cycles at a contact pressure of 1.1 GPa. Similarly, Wang et al [4] developed a multi-phase carbonaceous coating containing amorphous, fullerene-like, and nano-crystalline carbons using magnetron sputtering method, which exhibited an ultralow friction coefficient of 0.05 and a low wear rate of about 10 -8 mm 3 •N -1 •m -1 . Another research group synthesized graphite-like carbon (GLC) and fullerene-like carbon (FLC) films by different heating and cooling processes after plasma enhanced chemical vapor deposition (PECVD) [5].…”

A review of recent advances in tribology

et al. 2020

View full text Add to dashboard Cite

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…No mixing was observed between the Au and Ni layers for thinner multilayer samples under N 2 , in contrast with UHV. Despite the environment being nominally inert, the role of trace hydrocarbons can have a remarkable impact on friction behavior when the rubbing surfaces are wear resistant and smooth [31]. While we found deformation of the uppermost Au layers from plowing of material throughout sliding, material transfer from other areas in the contact was also occasionally observed, leading to thickening of the tribolayer.…”

“…For example, the adsorption of N 2 [28] and NO 2 [29] on Au surfaces has been observed, and the formation of N 2 O 3 via the adsorption of NO 2 has been seen on Au (111) [30]. Additionally, the presence of trace hydrocarbons has been shown to be more than sufficient to affect the friction of hard, smooth, and deformation resistant coatings [31]. Hence, the possibility of chemical interactions by hydrocarbons on the uppermost Au layers cannot be excluded in our experimental conditions.…”

Effect of Environment on Microstructure Evolution and Friction of Au–Ni Multilayers

We present results from a systematic investigation of environmental effects on the frictional behavior of Au-Ni multilayer films of varying interlayer spacing. The current results, sliding against ruby spheres in a dry N 2 atmosphere, are compared to prior work on the tribological behavior of these materials under ultra-high vacuum (UHV) (Cihan et al. in Sci Rep 9:1-10, 2019). Under both conditions, there is a regime of high friction when the interlayer spacing is large and a regime of low friction when the spacing is small. The low friction regime is associated with a critical grain size below which grain boundary sliding is expected to be the dominant mechanism of deformation. A shear-induced alloy formation (60-65 at.% Ni in Au) and a concomitant low friction coefficient was observed with multilayer spacings of 20 nm and lower under UHV. A distinct microstructure was found in dry N 2 , and is attributed to different interfacial characteristics due to adsorbed species; rather than mixing between Au and Ni layers, only the uppermost Au layers were affected by shearing. These observations are coupled with the friction and wear behavior of multilayer samples sliding under different environments.

“…The passive film is broken under the dirt particle deposited on the surface of the material or biofilms exposing the active metal to the corrosive attack. An electrical potential develops between the large area of the passive film and the small area of the active metal, resulting in rapid corrosion by pitting . This kind of bacteria may develop a symbiosis environment with other types of bacteria, fungus or yeasts to isolate the structure of the bottom of the tank and together with the other organisms neutralize the toxic materials and create an environment with anaerobic conditions and nutrients conducive to the growth of sulfate‐reducing anaerobic organisms.…”

In aircraft and storage fuel tanks, many environmental corrosion factors can be present, which can cause breakdown to the passive film of aluminum causing severe localized corrosion. Aiming to a solution to this problem, diamond-like carbon (DLC) films were deposited on substrates Al 2024-T3, Al 5052-H32, and Al 6061-T6. The substrates with and without DLC films were submitted to a corrosive immersion test with aviation fuel Jet-A1 and AVGAS 100LL. The surface morphology from aluminum substrates with and without DLC films was analyzed before and after 7 and 30 days of corrosive immersion tests by SEM. The adhesion of the DLC films was evaluated according to the ASTM-C1624 scratching test standard, and the optical profilometry was used to measure the thickness and roughness. Silver nanoparticles were also added in DLC films samples due to its antibacterial properties to check the stability and resistance against corrosive fuel medium. The results indicated an improvement of corrosion resistance just with DLC films. The silver nanoparticles did not present any advantages in this corrosion protection, and the aluminum alloys suffered more corrosion than when protected by DLC films.
