Abstract

Purpose

This paper aims to investigate the preparation of AlN and Al₂O₃, as well as the effect of nano-AlN and nano-Al₂O₃, on friction and wear properties of copper-steel clad plate immersed in the lubricants.

Design/methodology/approach

Nano-AlN or nano-Al₂O₃ (0.1, 0.2, 0.3, 0.4 and 0.5 Wt.%) functional fluids were prepared. Their tribological properties were tested by an MRS-10A four-ball friction tester and a ball-on-plate configuration, and scanning electron microscope observed the worn surface of the plate.

Findings

An increase in nano-AlN and Al₂O₃ content enhances the extreme pressure and anti-wear performance of the lubricant. The best performance is achieved at 0.5 Wt.% of nano-AlN and 0.3 Wt.% of nano-Al₂O₃ with PB of 834 N and 883 N, a coefficient of friction (COF) of approximately 0.07 and 0.06, respectively. Furthermore, the inclusion of nano-AlN and nano-Al₂O₃ particles in the lubricant enhances its extreme pressure performance and reduces wear, leading to decreased wear spot depth. The lubricating effect of the nano-Al₂O₃ lubricant on the surface of the copper-steel composite plate is slightly superior to that of the nano-AlN lubricant, with a COF reaching 0.07. Both lubricants effectively fill and lubricate the holes on the surface of the copper-steel composite plate.

Originality/value

AlN and Al₂O₃ as water-based lubricants have excellent lubrication performance and can reduce the COF. It can provide some reference for the practical application of nano-water-based lubricants.

纳米氮化铝、氧化铝对浸入润滑剂的铜-钢复合板的摩擦和磨损性能的影响

目的本文旨在研究 AlN 和 Al2O3 的制备以及纳米 AlN 和纳米 Al2O3 对浸入润滑剂的铜-钢复合板的摩擦和磨损性能的影响。结果纳米氮化铝和氧化铝含量的增加提高了润滑剂的极压和抗磨性能。纳米氮化铝（0.5 Wt.%）和纳米氧化铝（0.3 Wt.%）含量达到最佳性能，PB 分别为 834 N 和 883 N，摩擦系数（COF）分别约为 0.07 和 0.06。此外，在润滑剂中加入纳米 AlN 和纳米 Al2O3 颗粒可提高其极压性能并减少磨损，从而降低磨损点深度。纳米 Al2O3 润滑剂对铜-钢复合板表面的润滑效果略优于纳米 AlN 润滑剂，其 COF 达到 0.07。两种润滑剂都能有效填充和润滑铜钢复合板表面的孔洞。它可以为纳米水基润滑剂的实际应用提供一些参考。同行评议本文的同行评议记录可在以下网址查阅：https://publons.com/publon/10.1108/ILT-08-2023-0255/。
