“…According to the literature, the best wear-resistant microstructure is a pearlitic matrix with a tiny quantity of free ferrite. GCI includes such a matrix, and its use for a range of tribological applications has been seen in the past, particularly in sliding contact systems [8,9].…”

This research investigates the tribological behavior of gray cast iron against EN31 steel under lubricated conditions. The most typical lubricated sliding phenomena are the reduction of wear on both the sliding surfaces and any one of the critical surfaces. Static and hydrodynamic wear can be reduced based on fluid properties or the accessibility of fluid between the surfaces. The oil’s viscosity or content of the hydrocarbon and additives present in the oil plays a major role in controlling the wear of reciprocating surfaces. Therefore, this research work focused on metal-to-metal contact wear under the influence of lubricating oil (40 pride oil). The Taguchi method was used to select the sliding parameter combinations. Lubricated sliding resulted in a relatively reduced order of friction coefficient, attributable to better load distribution due to the formation of the lubricant film.

“…Such a matrix composition provides good wear resistance between the two sliding surfaces and in similar applications like brakes, cylinder liners, and piston rings. Another investigation describes the association of two distinct regions of grey pearlitic cast iron that were exposed during the dry sliding wear experimentation [11,12]. In the initial region of the crystal structure, the graphite dominates to mitigate the wear rate, and its graph has linear correlation.…”

Grey cast iron (GCI) and steel contact surface application is an inevitable component and provides good wear resistance in several applications, not only in automobiles. Grey cast iron consists of a predominantly pearlitic/ferrite matrix or both with graphite flakes. The majority of previous research works were based on three different types of wear regimes. The wear regimes enumerate the wear track morphology, wear rate, and COF of the respective application. In this research work, dry sliding wear properties of GCI and EN31 pins were examined with different sliding parameters using pin on disc wear test. The weight loss, coefficient of frictions, and surface morphology were considered for experimental analysis. Due to the transfer of wear debris from the GCI disc, the counter steel pin surface experienced a progressive reduction in wear with increasing speed and load. With 30 N and 45 N contact loads and sliding speeds up to 1 m/sec, the GCI shows marginally positive wear. The surface textures were analyzed with the help of SEM and a surface roughness tester.

The article presents an analysis of phenomena of selected elements of piston internal combustion engines cooperating with the combustion chamber and issues related to tribological aspects. It shows an attempt to assess the state of the tribological nodes: the valve stem – valve guide and valve head – valve seat in random natural conditions. Passive and passive-active experiments were conducted in the conditions of the operation of sea ships. The effects of complex and changeable inputs were examined on the value of the normal and pathological wear in the operation of medium-speed engines. Images of wear and damaged items of tribological nodes were studied. Analysis was conducted of digital images of real objects and using an optical microscope and measurements of macro- and micro-geometry. An identification of basic processes of wear was taken.
