“…During the wear process, graphite can be pressed into the friction pair and spread across the worn surface. This leads to the formation of a carbon layer, which provides lubrication [21]. However, as the wear test temperature increases, the carbon (C) in the graphite gradually oxidizes, generating gas and shedding from the friction pair.…”

In this paper, the friction and wear properties of gray cast iron with different carbon content at different ambient temperatures and the failure forms of gray cast iron friction and wear are studied. The research concludes that under low-temperature wear conditions, the graphite in the gray cast iron structure can enter into the interface between the friction pair, have a lubricating effect on the wear surface, and reduce the friction coefficient and wear loss of the gray cast iron material. As the graphite content in the gray cast iron structure increases, the lubrication and protection effect of the graphite increases, and the wear failure of gray cast iron is mainly caused by plastic deformation-induced fatigue peeling. Under high-temperature wear conditions, an oxide layer gradually forms on the wear surface. With the increase of experiment temperature, the thickness of the oxide layer increases on the wear surface. When the oxide layer formed on the wear surface reaches a certain level of thickness, the internal expansion stress of the oxide layer increases considerably, causing the oxide layer to peel off and increase the roughness of the wear surface, friction coefficient, and wear loss. Additionally, with the increase of the graphite content in the gray cast iron structure, the surface is more prone to oxidation, leading to the increase of friction coefficient and wear loss. The wear failure of gray cast iron is mainly caused by oxidation layer peeling.

“…Gray cast iron contains a large amount of ake graphite structure. During the wear process, graphite can enter the friction pair under the pressure of the mating pair, and spread on the worn surface, forming a layer of carbon accumulation on the worn surface, which plays a speci c lubricating role [11]. However, with the increase in wear test temperature, the C element that makes up the graphite gradually oxidizes, generate gas, and shed from the friction pair.…”

In this paper, the friction and wear properties of gray cast iron with different carbon content at different ambient temperatures and the failure forms of gray cast iron friction and wear are studied, which has a certain guiding significance for the manufacture of gray cast iron brake discs. The research concludes that under low-temperature wear conditions, the graphite in the gray cast iron structure can enter into the interface between the friction pair, have a lubricating effect on the wear surface, and reduce the friction coefficient and wear loss of the gray cast iron material. As the graphite content in the gray cast iron structure increases, the lubrication and protection effect of the graphite increases, and the wear failure of gray cast iron is mainly caused by plastic deformation-induced fatigue peeling. Under high-temperature wear conditions, an oxide layer gradually forms on the wear surface. With the increase of experiment temperature, the thickness of the oxide layer increases on the wear surface. When the oxide layer formed on the wear surface reaches a certain level of thickness, the internal expansion stress of the oxide layer increases considerably, causing the oxide layer to peel off and increase the roughness of the wear surface, friction coefficient, and wear loss. Additionally, with the increase of the graphite content in the gray cast iron structure, the surface is more prone to oxidation, leading to the increase of friction coefficient and wear loss.

In this work, the tribological properties of a novel iron‐based self‐lubricating composite as the tribopairs of a plunger pump were systematically studied on an end‐face tribometer, and the tribological mechanism was also revealed. The results show that the wear mechanism of the composite can be ascribed to adhesive wear when the sliding speed is lower than 1.5 m/s. As the sliding speed increases from 1.5 to 2.0 m/s, the wear type transforms to oxidative wear due to the increase of tribo‐oxidation. In addition, the failure criteria of the tribopair composite materials are summarised. When the average coefficient of friction is greater than 0.04, or the wear rate is greater than 9.66 μm3/(N m), the tribopair fails. This offers a valuable reference for industrial application of the tribopairs made from the iron‐based self‐lubricating composite.
