Purpose This paper aims to investigate the effect of chemical nickel plating and mechanical alloying on the mechanical and tribological properties of FeS/iron-based self-lubricating materials as well as the wear mechanism of the materials. Design/methodology/approach Surface modification of FeS powder was carried out by chemical nickel plating method and mechanical alloying of mixed powder by ball milling. The mechanical properties of the material were tested by tribological testing by M-200 ring block type friction and wear tester. Optical microscope was used to observe the surface morphology of the material and the transfer film on the surface of the mate parts, and scanning electron microscope and EDS were used to characterize the wear surface. Findings Mechanical alloying ball milling was carried out so that the lubricating particles in the matrix are uniformly dispersed; nickel-plated layer enhances the interfacial bonding of FeS and the matrix, and the combination of the two improves the mechanical properties of the material, and at the same time the friction side of the surface of the lubrication of FeS lubricant transfer film formed is denser and more intact, and the friction coefficient of friction side and the wear rate of the material have been greatly reduced. Originality/value This work aims to improve the mechanical and tribological properties of FeS/iron-based self-lubricating materials and to provide a reference for the preparation of materials with excellent overall properties.

“…However, Sn is shown to be the best alloying element for preventing Bi precipitation on the grain boundaries [ 28 ]. The optimal Bi content for bimetal bronze bearings operating under the boundary lubrication condition is 3 wt% of Bi [ 29 ]. The mechanical performance of bismuth bronze alloys, CuSn 10 Bi 4 and CuSn 6 Bi 6 in the thrust bearing tests concluded that Bi is not as good dry-lubricant as the lead in the tested alloys due to its poor bearing performance having both low load capacity and a high coefficient of friction (CoF) [ 30 ].…”

Solid Lubrication at High-Temperatures—A Review

Understanding the complex nature of wear behavior of materials at high-temperature is of fundamental importance for several engineering applications, including metal processing (cutting, forming, forging), internal combustion engines, etc. At high temperatures (up to 1000 °C), the material removal is majorly governed by the changes in surface reactivity and wear mechanisms. The use of lubricants to minimize friction, wear and flash temperature to prevent seizing is a common approach in engine tribology. However, the degradation of conventional liquid-based lubricants at temperatures beyond 300 °C, in addition to its harmful effects on human and environmental health, is deeply concerning. Solid lubricants are a group of compounds exploiting the benefit of wear diminishing mechanisms over a wide range of operating temperatures. The materials incorporated with solid lubricants are herein called ‘self-lubricating’ materials. Moreover, the possibility to omit the use of conventional liquid-based lubricants is perceived. The objective of the present paper is to review the current state-of-the-art in solid-lubricating materials operating under dry wear conditions. By opening with a brief summary of the understanding of solid lubrication at a high temperature, the article initially describes the recent developments in the field. The mechanisms of formation and the nature of tribo-films (or layers) during high-temperature wear are discussed in detail. The trends and ways of further development of the solid-lubricating materials and their future evolutions are identified.

To address the challenges of liquid metal embrittlement (LME) cracks and low bonding strength at the Sn bronze/steel liquid–solid compound interface, an innovative Sn bronze/Al bronze/steel laminated composite is fabricated using a wire arc additive manufacturing (WAAM) process, which involved introducing an Al bronze interlayer. The microstructure of interlayer and its related interfaces, as well as the mechanical properties of the composites, are investigated. Results show that the microstructure of Al bronze is mainly composed of α‐Cu and β‐Cu3Al. An interdiffused layer with a maximum thickness of 5 μm exists at the Al bronze/steel interface, which plays an important role in interface adaptation. The Sn bronze/Al bronze interface possesses a 30 μm α(Cu–Al–Fe) transition layer, and the continuous transition of α + β → α(Cu–Al–Fe) → α(Cu–Sn) from the base material to the clad layer is realized. No LME cracks are found in the steel after the Al bronze and Sn bronze deposition. The Al bronze/steel and Sn bronze/Al bronze interfaces exhibit strong bonding strengths of 395 and 361 MPa, respectively.
