Wear and frictional mechanisms of copper-based bearing alloys

Abstract: a b s t r a c tThe present study investigated the role of alloy microstructure and surface roughness on wear and friction behavior of leaded and unleaded tin bronzes. Ball-on-disk experiments were carried out under dry conditions with steel balls sliding against bronze disks. Scanning electron microscopy (SEM), energy dispersive electron microscopy (EDX), x-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy were performed to analyze the sliding tracks and the ball scars. The wear reducing eff… Show more

“…Even without any further heat treatment, which is only possible for the CuNi9Sn6 alloy, the MIM produced samples show less friction and wear. These differences are mainly attributed to the different ability of the subsurface zone to deform plastically 15 and thus partially dissipate friction energy. Additionally, it is obvious that the formation of a system specific microtopography in the contact zone is significantly controlled by microstructural features.…”

“…15, subsurface deformations essentially influence frictional behaviour. Both materials exhibit a relatively high increase in the cof at the beginning of the test, followed by a pronounced decrease leading to quasi-constant cof levels towards the end of the tests.…”

“…The conductivity, thermal conductivity and strength of copper alloys is often an inverse relationship. Depending on the number of constituent elements, alloy can be divided into binary alloys, ternary alloys and multicomponent alloys . This review, mainly refers to alloys such as binary alloy, multi‐component alloy, alloy composites with carbon source and so on.…”

“…Often a tribological event is characterized by the movement, or articulation, between two bodies. Corrosion is typically distinguished by an electrochemical process that generally takes place under a stable environment with an exposed surface [8][9][10][11]. Implementing the synergistic interaction of tribology and corrosion is the novel aspect of the area of tribocorrosion research.…”
