Abstract
A wear-resistant composite material based on aluminum bronze with an addition of tungsten and tungsten carbide particles is developed using a combined wire- and powder-feed additive electron beam technology. The wear tests conducted under dry sliding conditions at room and elevated temperatures demonstrate a significant increase in wear resistance without any significant changes in the friction coefficient. Specifically, the composite with a particle content of 10 % exhibits an average wear rate 1.6 times lower compared to that of pure aluminum bronze, while the composite with a particle content of 20 % shows a 3.9-times wear rate reduction. The wear of the steel counterfaces during the composite sliding remains close to the values observed in a similar process for pure bronze.
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.
