“…Sang et al [7] reported that SiC ceramic composite prepared by infiltrating molten fluoride and nickel into the ceramic preforms showed low friction coefficients at high temperature. Preliminary experiments have revealed that the physical properties of such composites depended to a large degree on the properties of preforms [8] and the tribological properties was based on squeezing the lubricant phase out, which led to the formation of a surface film protecting the friction surfaces against seizure and scoring (self-lubrication effect) [9]. The present work represents a new approach in producing selflubrication metal ceramic composites with an interpenetrating network.…”

“…Normally, tin and lead are the main alloying components for aluminum antifriction alloys [15][16][17][18][19][20][21][22][23][24]. Particularly, Al-20Sn-1Cu alloy is acknowledged to be a basic alloy for the development of new antifriction materials due to its good tribological behavior.…”

Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

et al. 2020

In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive analysis (EDX), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction analysis (XRD). In addition to the mass transfer of steel counterbody particles, phase transformations and new chemical compounds formed as a result of interaction with the lubricant were revealed. The release of elements, mainly magnesium and to a lesser extent zinc, from a solid solution of aluminum alloy was also observed, which indicates the occurrence of a non-spontaneous reaction with a negative entropy production.

“…In these works, the features of these alloys are considered-the extraction of a soft phase from a solid matrix, mass transfer from one friction surface to another, the formation of a film of secondary structures (SS). In Bushe et al (2003), the authors presented an improved model of the process of separating the soft phase from the antifriction alloy. This model takes into account the fact that the amount of plastic phase that forms the SS film depends on the nature and strain value of the matrix itself.…”

Tribological Tests Effect on Changes in the Surface Layers of Iron-Containing Antifrictional Aluminum Alloys

et al. 2019

Antifrictional properties and surface parameters of Al-Si-Cu-Sn-Pb alloys have been investigated. The effect of iron addition (∼1%) on the structure and tribological properties of aluminum alloy samples has been studied. Tribological properties were explored using the "shoe-roller" scheme with step-by-step pressure changes. The investigations were carried out both in and without a lubricant. The SEM-(with elemental analysis) and SPM-microscopy methods were applied to study sample surface and under-surface layers of the samples at the transversal sections. After tribological tests have been carried out, the topography of both surface and under-surface layers at the transversal sections has been studied. During the tests without lubrication solid particles, presumably, oxides were formed. The particles increase the surface destruction, thus, doing their part of an abrasive and contributing to (scuffing) score. After testing in the lubricant particles containing silicon and copper and having a rounded shape were also formed. These particles remain on the surface and are rolled in the lubricant. They creating a kind of a "protective cover" contributing to the contact pair stable operation. The under-surface layer 50-100 µm thick formation was found at the sections after tribological tests without lubrication. The samples sections were prepared after testing with lubrication. The study of the samples sections demonstrated the formation of the under-surface layer with thickness 30-40 µm. The elements redistribution in these layers was shown. After the tribological tests were carried out, the counterbodies (rollers) were also explored. The SPM method has been shown the film formed on the surface is uneven in thickness after tests without lubrication. This leads to the macrorelief development during friction and can lead to (scuffing) score. On the contrary, after tests in lubricant the secondary structures film formed is distributed on the surface as a thin uniform layer. This film has the protective properties. It was shown that alloys containing iron (up to 1%) have good tribological characteristics when tested both in and without the lubricant. Thus, they can be used as antifrictional materials.
