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AlN、Al2O3对润滑剂浸铜钢复合板摩擦磨损性能的影响

目的

本文旨在研究AlN和Al ₂ O ₃的制备以及纳米AlN和纳米Al ₂ O ₃对浸泡在润滑剂中的铜钢复合板摩擦磨损性能的影响。

设计/方法论/途径

制备了纳米AlN或纳米Al ₂ O ₃ (0.1、0.2、0.3、0.4和0.5重量％)功能流体。采用MRS-10A四球摩擦试验机和球盘结构测试其摩擦学性能，并通过扫描电子显微镜观察板的磨损表面。

发现

_{纳米AlN和Al 2} O ₃含量的增加增强了润滑油的极压和抗磨性能。在0.5 Wt.%的纳米AlN和0.3 Wt.%的纳米Al ₂ O ₃下实现了最佳性能，PB为834 N和883 N，摩擦系数(COF)分别约为0.07和0.06。此外，润滑剂中包含纳米AlN和纳米Al ₂ O ₃颗粒可增强其极压性能并减少磨损，从而减少磨损点深度。纳米Al ₂ O ₃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，COF达到0.07。这两种润滑剂都能有效地填充和润滑铜钢复合板表面的孔洞。
