“…The heat treatment of the steel was performed prior to machining to size (the details of this heat treatment process can be found elsewhere [21]) and resulted in the specimens having a hardness (HV 20 ) of 465-480 kgf mm −2 .…”

“…At both frequencies, the debris formed at the centre of the contact was dominated by titanium nitride rather than titanium oxide, with the latter being the primary debris surrounding the very outer region of the contact. The formation of titanium nitride indicated that the area of the contact was depleted in oxygen, indicating that ingress of the atmosphere into the contact is a critical process in the development of fretting damage [20]. Addressing the frequency effect, Van Peteghem et al [6] argued that a decrease in fretting frequency would decrease the frictional power dissipated in the contact, and thus the temperature of the contact would also decrease.…”

Fretting wear mapping: the influence of contact geometry and frequency on debris formation and ejection for a steel-on-steel pair

2015

This paper examines the influence of contact geometry and oscillation frequency in a steel cylinder-on-steel flat fretting contact, with contact geometry being varied via the cylinder radius. Fretting frequency did not significantly impact the wear behaviour for more-conforming contacts, but did so for less-conforming contacts where, at high frequency, the wear rate is approximately 50% of that observed for low-frequency fretting. It is proposed that frequency and contact conformity fundamentally control wear behaviour through influence of both the debris type and the retention or ejection of that debris from the contact. The debris type (either oxide or metallic) is influenced by fretting frequency (which controls the interval between asperity contacts) and by contact conformity (which controls the distance that oxygen has to travel to fully penetrate the contact). Debris retention within the contact is promoted by higher fretting frequencies (the associated higher contact temperature promotes debris agglomeration and sintering in the contact) and by higher contact conformity (which acts as a physical barrier to debris egress). Maps are presented which categorize the observed behaviour and outline a phenomenological framework by which the basic physical processes which influence fretting behaviour can be understood.

“…In the case of a polymer loaded with MoS2 particles, the coating is often applied on top of a metallic bond layer (typically Cu-Ni-In) [20] which is itself deposited onto the component surface by thermal spraying. The Cu-Ni-In layer performs a number of functions, the most significant of which is that it is thought to act as a retainer for the polymeric DFL [3].…”

This work investigates the behaviour of a commercially available MoS2-based DFL in a cylinder-on-flat contact geometry with a fretting amplitude of 300 µm. Cylinders with radii of 15 mm, 80 mm and 160 mm along with DFL thicknesses between 12 µm and 86 µm were utilized. Three stages in the lifetime of the system were investigated; in the first stage, the DFL wore with a volumetric rate that was proportional to the number of cycles (under a given load), until the thickness of the DFL was reached. In the second stage, a thin low friction surface layer existed, with its durability being proportional to the contact pressure. In the third stage, metal-metal contact resulted in short-term instabilities in the coefficient of friction and the DFL system was said to have failed.

RAMAZAN OG UZHAN APAYDIN, BURÇ AK EBIN, and SEBAHATTIN GÜ RMENNanostructured copper-nickel (CuNi) and copper-nickel-indium (CuNiIn) alloy particles were produced from aqueous solutions of copper, nickel nitrates and indium sulfate by hydrogen reduction-assisted ultrasonic spray pyrolysis. The effects of reduction temperatures, at 973 K, 1073 K, and 1173 K (700°C, 800°C, and 900°C), on the morphology and crystalline structure of the alloy particles were investigated under the conditions of 0.1 M total precursor concentration and 0.5 L/min H 2 volumetric flow rate. X-ray diffraction studies were performed to investigate the crystalline structure. Particle size and morphology were investigated by scanning electron microscope and energy-dispersive spectroscopy was applied to determine the chemical composition of the particles. Spherical nanocrystalline binary CuNi alloy particles were prepared in the particle size range from 74 to 455 nm, while ternary CuNiIn alloy particles were obtained in the particle size range from 80 to 570 nm at different precursor solution concentrations and reduction temperatures. Theoretical and experimental chemical compositions of all the particles are nearly the same. Results reveal that the precursor solution and reduction temperature strongly influence the particle size of the produced alloy particles.
