Abstract
In this work, the microstructure and tribological properties of coarse-grained nickel aluminum bronze (NAB) alloys with different ratios of α/β′ phases were studied at room temperature. For revealing the intrinsic tribology behavior, the hard SiC sanding disc with a microhardness of 2400∼2800 HV, almost 10 times higher than that of the NAB alloy, was selected as the counter material. The tribological behavior was investigated using multiscale characterization, including macroscale X-ray diffraction (XRD) and laser scanning confocal microscopy (LCM), microscale scanning electron microscopy (SEM), as well as nanoscale transmission electron microscopy (TEM). The findings reveal that abrasive wear predominates in these samples, with delamination, oxidation, and fatigue wear also present. Notably, the dual-phase alloy exhibits inferior wear resistance compared to the single-phase alloy, attributed to the alternating-wear process of the two phases. Additionally, we observed the in-situ formation of a nano oxide film during the friction process, highlighting its significant role in enhancing the wear resistance of NAB alloys through a self-lubricating effect.
期刊介绍:
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
