“…In the dry condition of surface contact, the normal wear that occurs in GCI is quite high, and the same was stated by Chawla et al [14] in their experimentation. At an increasing sliding speed, wear was attributed more to stainless steel, and it was softened during its increasing load factor.…”

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.

“…Simultaneously, due to three-body abrasion, the hard carbide particle present in debris generation started along the wear track, preventing material loss during sliding. Chawla et al [12] investigated the GCI wear mechanism, using the pin-on-disc wear tests under dry sliding conditions. The results show greater wear in stainless steel 304 with an increase in sliding speed at normal load and getting softened with an increase in the load parameter.…”

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.

“…Due to the low durability of iron-based materials at low temperatures, cast iron brakes have been shown to wear down quickly. Furthermore, as cast iron's worn graphite transforms into a solid lubricant, the friction coefficient is decreased (Chawla et al, 2013). Investigations were done on the wear properties of grey cast iron, AISI NO.35B (JIS FC250).…”

Introduction: The performance functionality efficacy of the engine’s valve train assembly is considerably affected by the valve guide. Material selection is impacted by the prolonged operational lifespan of engines, which favours casting and machining materials such as cast iron. The intent of this study is to examine the dry sliding characteristics of GG25 cast iron with copper additives. Discovering the ways in which variations in load and sliding velocity impact wear characteristics is of paramount significance.Methods: The research entailed the examination of wear characteristics across various environmental conditions. Loads were varied at 30 N, 40 N, and 50 N while maintaining a 1 m/s velocity constant. In the same manner, sliding velocities of 0.5 m/s, 1 m/s, and 2 m/s were varied while a constant load of 30 N was maintained. Experimental techniques were carried out at ambient temperature. Throughout the investigations, frictional forces and the coefficient of friction were also determined. The wear mechanisms of samples that had become deteriorated or worn-out were examined by employing a scanning electron microscope when combined with EDX analysis.Results: A rise in the normal load from 30 N to 40 N led to a twofold rise in wear losses, measuring 417 microns as compared with 222 microns previously. The range of wear losses observed at moderate speeds (0.5 m/s–1 m/s) was 133–222 microns. Conversely, the maximum wear loss observed was 1,226 microns at elevated sliding velocities of 2 m/s, in contrast to 617 microns at higher normal loads of 50 N. Additionally, the research discovered that normal load is more pronounced when both loading and speed are moderate, whereas sliding speed becomes more substantial when both are raised, culminating to higher wear losses.Discussions: In summary, the research highlights the considerable effect that normal load and sliding speed have on the prevalence of wear losses. In conditions of moderate loading and velocity, the influence of normal load is more significant. However, as sliding accelerates, it becomes the predominant factor. An analysis of frictional forces as well as the coefficient of friction indicated that under loading conditions of 30 N–50 N, the friction coefficient raised from 0.238 to 0.43. The wear mechanisms, as discerned via scanning electron microscopy and EDX analysis, underscored the considerable impact of increased sliding velocity on wear loss in comparison to conditions of higher loading.
