The correlation between friction coefficient and areal topography parameters for AISI 304 steel sliding against AISI 52100 steel

Abstract

Dry wear experiments provide an insight detail on how severely contacting surfaces change under unlubricated sliding condition. The theory of dry sliding wear is used for understanding mixed-lubrication regime in which asperity interactions play a significant role in controlling of the friction coefficient (f). The purpose of this work is to study the tribological behavior of AISI 304 steel in contact with AISI 52100 steel during wear. Both materials are used in rolling element bearings commanly. Experiments are carried out using a pin-on-disc tribometer under dry friction condition. The areal (three dimensional, 3D) topography parameters are measured using a 3D white light interferometer (WLI) with a 10× objective. After wear tests, wear mechanisms are analyzed utilizing scanning electron microscope (SEM). Factorial design with custom response surface design (C-RSD) is used to study the mutual effect of load and speed on response variables such as f and topography parameters. It is observed that the root mean square roughness (Sq) decreases with an increase in sliding time. Within the range of sliding time, Sq decreases with an increase in the normal load. Within the range of sliding speed and normal load, it is found that Sq, mean summit curvature (Ssc), and root mean square slope (Sdq) are positively correlated with f. Whereas, negative correlation is found between f and correlation length (Sal), mean summit radius (R), and core roughness depth (Sk).

Sliding abrasive wear when combining WEDM conditions and polishing treatment on H13 disks over 1045 carbon steel pins

“…There is evidence of wear track on the disks that had a roughing WEDM condition, and the curve for the pin revealed a degradation that quickly overgrew. In 2 min of testing, the diameter of the pin footprint reached 70% of its final diameter compared to the diameter found at 40 min, similar to Prajapati et al [31] when studying pin-on disk of short duration. SEM images revealed that abrasive wear and plastic deformation processes are present in every surface configuration (see Fig.…”

“…The hardness values of the disks were 505 ± 13 HV. The disks were hardened and tempered to obtain similar hardness values than [31]. The surfaces of the disks were WEDM [15] (Novick AR 35 MA) by using two operational conditions: half of them in a finishing condition (t on = 5 μs; t off = 34 μs; T = 39 μs; f = 25.6 Hz; t on /T = 0.13; V = 4 V), and the other half in a roughing condition (t on = 50 μs; t off = 180 μs; T = 230 μs; f = 4.3 Hz; t on /T = 0.22; V = 6 V).…”

A review of advances in tribology in 2020–2021

“…The wear particles grew into rolling cylinders and into larger aggregates, which took the form of flakes, creating a third-body layer and the macroscopic roughness. The monotonic decreasing in friction coefficient, monotonic or non-monotonic changes in surface roughness and other topographic features as well as gradual work hardening have also been reported during different types of tribopairs [354][355][356][357].…”

Differentiation of specific wear rates of AISI 304 austenitic and AISI 2205 duplex stainless steels at room and high temperatures

“…Among stainless steels (ASS), austenitic grades, and specially AISI 304 has the most used in bearings, chemical industries, and surgical and marine equipment ( Prajapati and Tiwari, 2021 ; khaleal et al., 2020 ). Although their excellent corrosion resistance, their low yield strength restricts applications in harsh environments and may necessitate searching for a suitable substitute ( Avilaa et al., 2020 ; Alabdullah et al., 2016 ; Moharana et al., 2016 ).…”
