High-Temperature Friction and Wear Studies of Nimonic 80A and Nimonic 90 Against Nimonic 75 Under Dry Sliding Conditions

Abstract

The present research focuses on dry sliding friction and wear behaviour of Nimonic 80A and Nimonic 90 against Nimonic 75 at high temperature up to 1023 K. The influence of temperature, sliding distance and normal load on friction and wear behaviour of Nimonic 80A and Nimonic 90 against Nimonic 75 was studied using pin (Nimonic 75)-on-disc (Nimonic 80A and Nimonic 90). Lower wear and lower friction of superalloys was observed at high temperatures, as compared to room temperature. Surface morphological and surface analytical studies of fresh and worn surfaces were carried out using optical microscopy, 3D profilometer, scanning electron microscope, energy-dispersive X-ray spectroscopy and Raman spectroscopy to understand the friction and wear behaviour. The mechanism of the formation of microscale glaze layer is also discussed.

Effect of the Normal Load on the Friction and Wear Behaviour of Nickel-based Alloys Ni-Cr-B-Si-C-W

“…Some works have been devoted to these alloys focusing mainly on the study of their mechanical properties or the evolution of their metallurgical structures under the effect of adding certain elements. Others [12][13] go to compare them and the nickel super alloys elaborated or obtained from mechanical pieces, they show the comportment of the RESEARCH friction and wear when hard layer are formed. Nickel based alloys is composed mainly of nickel (matrix), metallic (Cr, W) and no metallic (B, C and Si) elements that favour the creation of the hard phases such as chromium carbide and chromium boride.…”

It is used for sheet applications calling for oxidation and scaling resistance coupled with medium strength at high operating temperatures [13].…”

Dry tribological properties of M50 bearing steel under different temperatures

“…In fact, the process of forming and breaking tribolayer is a dynamic balance state on the wear surface during the sliding friction tests [25][26][27]. The wear surface is broken under the combined actions of shearing stress and oxidation, and the particles fall off from the matrix, leading to the formation of the spalling pits [28,29] Some of the particles escape out of the wear surface and form wear debris, and others are filled in the spalling pits and compacted again to restore the tribolayer.…”

High-Temperature Tribological Behavior of Al0.3Cr0.5Fe1.5Mn0.5Ni High-Entropy Alloys With Addition of Titanium and Carbon

“…The better oxidation resistance exhibited by alloys leads to the formation of a denser oxide layer, the lubrication mechanism such as self-lubrication were also shown in several alloys (Pei et al, 2005;Deng et al, 2007). Several studies have been conducted on the tribological performance of traditional alloys at elevated temperatures (Birol, 2010;Inman and Datta, 2011;Cheng et al, 2017;Khajuria and Wani, 2017); the mechanism of glazed layer has also been well-researched (Stott et al, 1973;Stott, 1998;Jiang et al, 2004). The main objective of the present work is to investigate the tribological behavior of high-entropy alloys (HEAs) at elevated temperatures.…”
