This work investigated the effect of honing morphologies of CuNiCr iron liner on its tribological properties sliding against the Cr-Al2O3 coated piston ring. The worn surface morphology and elements distribution as well as the wear behaviors of CuNiCr iron liner were analyzed to explore the influencing of the honing angle and roughness height on the friction and wear resistance. The results show that the optimized honing angle and roughness can improve the tribological performance of the iron liner, and different tribological characteristics are closely related to different roughness parameters. The wear process of the CuNiCr iron liner against Cr-Al2O3 coated piston rings in sequence was platform flattening, plastic flow, growth of the flakes on the platform edge and flakes debonding. For the smooth surface, the plastic deformed flakes were much fewer due to the low height of the platforms, thus the grooves were not fully filled and there was a slight effect of the debonded debris on the friction pair.

“…It is actually cast iron whose structure lies in the metal matrix and consists of graphite lamellae. The improvement of wear-resistant properties of a cast iron piston ring-cylinder liner pair of an internal combustion engine can exert a significant influence on maintaining service properties, extending service life, and reducing the repair costs [22,23,24].…”

This research paper discusses preventive protection of the marine engine against abrasive effects of the catalyst fines in fuel. The relevant facts were gathered while analysing the performance of the slow-speed Wärtsilä RTA engine on an Aframax tanker. The analysis comprised fuel properties, regular and extraordinary examinations of the engine, including the control and replacement of piston rings and the measurement of the liner wear rate. The research particularly focused on the top compression ring as it withstands highest loads and fastest wear. On the other side, the research involved a chemical analysis of the piston rings with the purpose of establishing their chemical properties, structure, coating thickness and micro-hardness. In addition to a number of preventive measures that can be taken on board before injecting the fuel into the combustion chamber, the selection of a piston ring's material quality affects its wear rate to a large extent. The wear rate also depends on the catalyst fines in fuel. In practice, the piston ring of GGV type proved to be resistant to abrasive wear and its chemical properties were established through laboratory material testing.

“…One of them focused on wear and coefficient of friction on cylinder liner piston ring on the gray cast iron materials. 3 The results showed that the steady-state wear rate was lower for the piston ring which has the cylinder liner. Aaron et al studied the tribological performance of a flat piston ring prototype with partially textured surface by experimental method.…”

Cast iron is widely used due to low price, good machining and good damping capability. However, it has huge friction. In certain automotive components such as cylindrical liner, cast iron is used. The biggest challenge in cylinder liner is obtaining lower friction and wear. The main aim of the paper is to experimentally investigate the characteristics of wear induced by the sliding contact piston ring cylinder liner without lubrication. The modified material of spherical graphite cast iron has been explored. The indenter load, hardness and wear are of main particular interest. The pin on disk tribotester is used to obtain the characteristics of wear volume, wear width and wear depth. The other purpose of this research is to observe the characteristics of cylinder liner wear of spheroidal graphite cast iron from Klaten, Indonesia. The results show that low indenter load causes wear depth and volume. This finding is in a good agreement with published works. In addition, it is found that the material hardness also greatly affects the wear depth, wear volume and wear width.
