In internal combustion engines, friction losses caused by piston ring and cylinder liner pair account for approximately 20% of total mechanical friction losses as reported in literature. A reduction in friction between piston ring and cylinder liner pair would therefore result in higher efficiency, lower fuel consumption and reduced emissions. In this study, the effects of different types of fuel which is contaminated to cylinder oil have been tested for investigating the friction behavior between piston ring and cylinder liners pair by a reciprocating tester depending on the load, revolution and temperature. The results showed that lubricant type and revolution have been found significant on friction behavior.

“…To predict tribological behaviours of H-DLC coatings that will be applied to machine components, the correlations between tribological characteristics of particular H-DLCs coatings and working conditions are of paramount importance. Accordingly, the pin-on-plate configuration, pin semi spherical ends, and the range of normal loads used were intended to emulate the sliding conditions of a piston ring contact of internal combustion engine [29]. The initial Hertzian contact pressure used in this study and the experimental running conditions are shown in Table 2.…”

and 5.5 x 10 -8 mm -3 /N m, respectively. Through Raman spectroscopy and electron microscopy it was confirmed the carbon-carbon contact, due to the tribolayer formation on the wear scars of the coating and pin. In order to further corroborate the experimental observations regarding the graphitisation behaviour, the existing mathematical relationships to determine the graphitisation temperature of the coating/steel contact as well as the flash temperature were used.

“…Previous literatures showed that the size and number of defects in the coating affected the roughness [17,18]. In this study, there are many defects inside the sprayed coating, such as unmelted particles, voids, inclusions, and so on, which can increase the coating surface roughness.…”

e self-fluxing NiCrBSi coatings with 800 μm thickness were prepared on the surface of AISI1045 steel substrate by plasma spraying. And the remelted coating was obtained using by the tungsten inert gas (TIG) arc process. e microstructure, surface roughness, hardness, phase composition, and wear resistance of the sprayed coating and remelted coating were systematically investigated. e results demonstrate that TIG remelted treatment can significantly eliminate the microscopic defects in thick coating and improve its density. e surface roughness (Ra) of the remelted coating is only 18.9% of the sprayed coating. e hardness of the remelted coating is 26.8% higher than that of the sprayed coating. e main phases in the sprayed coating are changed from γ-Ni, Cr 7 C 3 , and Cr 2 B to γ-Ni, Cr 23 C 6 , CrB, Ni 3 B, and Fe 3 C. e wear mass loss of the remelted coating is only 17.1% of the sprayed coating. erefore, a Nibased thick coating with good wear resistance can be obtained by plasma spraying and remelted technique.
