Novel Composite Antifriction Bronzes: Composition, Structure, Properties (A Review)

Abstract

Results of studies of novel composite antifriction bronzes reinforced with dendrites represented by steels of different classes i.e., maragingμ, austenitic and stainless ones, are presented. The principle of creation of such materials and the chemical compositions of the developed composite bronzes are described. Their structures, mechanical properties, and heat treatment modes are characterized. It is shown that copper is highly soluble in iron (≥ 20 wt.%). The wear resistance of bronze BrZhNKhK 12-7-5-1 under sliding friction is shown to be five times higher than that of the classical bronze BrO10; after dispersing, the figure is ≥ 10 times. © 2023, Springer Science+Business Media, LLC, part of Springer Nature.
