“…EN590 and GDK650 as lubricants in the pin-on-disc model during the testing of wear behaviour of hydrogenated diamond likecarbon (DLC) coating in DLC/steel. It was concluded that anti-wear additives were harmful to DLC influencing its wear rate while steel remains unaffected by pressure, temper ature, speed and type of lubricant used [22]. The investigation was conducted to analyse the tribological properties of ground, lapped and textured lapped discs against polished pins for reciprocating motions.…”

This paper reports the findings of an experimental study pertaining to the tribo dynamic investigations of contacts formed between chrome base pin and cast iron/chrome plated cast iron discs in situ conditions. Pin on disc geometrical configurations were employed for conducting the experiments at different operating parameters using SAE-15W40 lubricating oil. The fully flooded lubricating condition was insured by directed supply of lubricant at the interface. The friction coefficient, wear rate, vibration amplitude, temperature rise and sound intensity were measured at different loads (varying in the range of contact pressure 1.9-3.1 MPa) and sliding speeds (2-10 m s −1 ) for the travelling distances between 1000-5000 m. Based on experimental investigations, reductions in the friction coefficient and wear rate were recorded for the chrome steel pin/chrome plated cast iron disc in comparison to chrome steel pin/cast iron disc contact. However, increases in the temperature rise, vibration, and noise were recorded with chrome steel pin/chrome plated cast iron disc contact.

“…There are sensitive highly optimized coating systems in modern fuel pumps and injectors for cars. Pump and injector design rely on the diesel fuel lubrication [16][17][18]. Slight reduction in fuels lubricity can lead to numerous fuel injection failures with adhesive sliding wear and scuffing (serve adhesive wear) due to rapid loss of fuel lubrication performance.…”

In this paper, two kinds of different biodiesel were tested in terms of their impact on wear resistance of Si-DLC coated 100Cr6 flat worn by an oscillating 100Cr6 ball. The knowledge about the tribological behaviour of different types of biodiesel is rare. Rape and soybean are two of the most common natural sources for biodiesel production. Also, if the quality of biodiesel seems to be similar and, according to the demands, biodiesel from different natural origin could affect changes in the tribological behaviour. Although, soybean methyl ester (SME) gives the best results at room temperature wear tests, 150 ∘ C SME reaches wear rates of Si-DLC flat against 100Cr6 ball almost double as high as rapeseed methyl ester (RME). It is evident that, with increasing fraction of oxidation stabilizer C 23 H 32 O 2 , the wear rate increases. For silicon doped hydrogenated diamond-like carbon is especially suitable, for use in biodiesels, where certain fraction of humidity, dissociated water, or polar functional groups may present.

“…The usage of various lubrication media such as water, oils, fuels and others in pin-ondisc tribological testing has been described for pure amorphous or diamond-like carbon coatings and for metal containing amorphous carbon coatings (usually for coatings with lower metal concentration (see exemplarily [77,78] and various articles in section B in [79], while fewer studies are available for nanocomposite carbide/amorphous carbon coatings with significant volume fraction of both phases. Zhang et al [17] reported wear studies in pin-on-disc tests of TiC/a-C nanocomposite coatings against a steel ball counterpart (100Cr6) in both unlubricated (i.e., in air with 75% relative humidity, at 22 • C, specified as dry conditions) and lubricated conditions.…”

Friction and wear performance of non-reactively magnetron-sputtered hydrogen-free TiC/a-C coatings were characterized under lubricated oscillating sliding conditions against 100Cr6 steel. The friction mediators, isooctane, ethanol and distilled water, were chosen to address the actual trend of environmentally friendly green technologies in mobility and the potential use of carbon-based nanocomposite thin film materials for tribocomponents in contact with gasoline and alternative biofuels. Sliding pairs of the TiC/a-C coatings showed significantly reduced friction and wear compared to the reference materials under both unlubricated and lubricated conditions (when using the aforementioned media isooctane, ethanol and distilled water). Quasi-stationary friction coefficient of the TiC/a-C sliding pairs after running-in was almost independent of test conditions and could be traced back to self-lubrication as a result of the formation of a transfer layer on the steel counter body. Wear of the coatings based on micro-abrasion and tribochemical reaction was significantly influenced by the environmental conditions. Lowest wear was measured after tests in non-polar isooctane whereas highest wear was measured after tests in water.
