Abstract
The influence of modification by ultradispersed materials on the structure and physicomechanical properties of alloys is considered. Nanostructured boron nitride and aluminum hydroxide monohydrate (boehmite) are chosen as modifying additions to study their influence on the structure formation in a zinc–aluminum–copper antifriction alloy. Scanning electron microscopy and electron-probe microanalysis are used to identify high-hardness phases in the alloy structure. Modifying particles are found to affect the hardness of the alloy, which increases significantly with the number of particles. The strength of the alloy depends on both the number and the size of introduced particles, and powders with small grain sizes are more effective to increase the strength of the alloy. Moreover, silicon carbide is shown to exert a stronger effect on the strength of silumins than alumina does.
