“…Such transition is coupled with a quick increase of the wear kinetics as discussed in section 3.1.2. This transition was confirmed by Elleuch et al [15] in brass and by Saka et al [16] in steel and was attributed to a complicated wear mechanism.…”

Magnesium is the lightest metal used in structural applications, such as aerospace industry, and therefore, it provides the greatest potential for weight or energy reduction. It is particularly suitable for transport technology applications. In order to substitute aluminium alloys in aeronautical engines, wear behaviour of magnesium alloys is considered. A comparison of the unlubricated wear resistance of an aluminium alloy (A 357) and two magnesium alloys (AZ 91 and WE 43) rubbed against 52 100 bearing steel in a pin-on-ring configuration over a range of sliding speed (1 -7 m/s) and applied normal loads (20 -80 N) is established. In addition to the measurement of the friction force and wear depth, the temperature near the sliding contact is also measured using a thermocouple placed at the back of the pin sample. Thermal effect on friction and worn surfaces are observed and characterized. Wear transitions are found for the AZ 91 and the A 357 alloys. These transitions are controlled by critical temperatures at the contact surfaces. Scanning electron microscopy observations and profilometric analyses are conducted to confirm these transitions and identify the wear mechanisms.

“…5,43 In the case of brass material, there could be coating process occurring during the sliding, which assist to cover the stainless steel counterface during the sliding resulting in very low material removal. 44 Another thought could be that the hardness of brass debris might not be as hard as mild steel debris, which in turn resulted in low material removal from the sample surface. To understand this further, elaboration regarding this point will be given in the surface observation section.…”

Understanding the wear mechanism significantly contributes to the knowledge of tribology of common metals and assists in predicting, overcoming and preventing the failure of designed components. In the current study, wear and frictional performances of brass, aluminium and mild steel metals are investigated at different operating parameters, i.e. sliding durations (0–10 km) and applied loads (0–50 N) against stainless steel counterface under dry contact conditions. The experiments were performed using block on ring machine. To categorise the wear mechanism and the damage features on the worn surfaces and the collected debris, scanning electron microscopy was used. Thermal imager was used to understand the heat distribution in the contacted bodies and the interface regions. The results revealed that the operating parameters influence the wear and frictional behaviour of all the metals. Brass metal exhibited better wear and frictional behaviour compared to others. Three different wear mechanisms were observed, i.e. two-body abrasion (brass), three-body abrasion (aluminium) and adhesive (mild steel).

“…Elleuch et al [32] determined the friction coefficient of 0.05, wear rate of 10 mg in SAE 619 brass Zeren [33] and Feyzullahoglu et al [34] determined the friction coefficient of approximately 0.05, wear rate of 10 mg in SAE 619 brass (2.4% Pb, 0.2% Sn, 39.5% Zn) and friction coefficient of approximately 0.06, wear rate of 20 mg in WM-2 (89% Sn, 7.2% Sb, 3% Cu) bearings at 1500 rpm sliding speed and 115 N loads, on dry and lubricated conditions. They reported that Sn element increased embability of bronze, brass, and Sn based bearings.…”

“…They reported that good wear performance of bearing was obtained because lead acts as an additional lubricant. Elleuch et al [32] have observed delamination and wear tracks on surfaces of brass bearings. Zeren [33] and Feyzullahoglu et al [34] have observed embability of Sn element.…”
