“…Aluminum Matrix Composite (AMC) materials have been found widely applied in mechanical engineering, instrument making, aircraft engineering, and space technology [1]- [8]. An important advantage of AMC is the possibility of their formation for specific operating conditions, due to the introduction of high-strength high-modulus fillers of various types, fractional composition, and volumetric content into a plastic metal matrix.…”

Hardness and tribotechnical characteristics were investigated under conditions of dry sliding friction on steel obtained by liquid-phase mixing of Aluminum-Matrix Composite (AMC) materials based on aluminum alloys AK12, D16, V124, AL9, AL25, reinforced with silicon carbide SiC particles with a size of 28 μm with a content of 5, 10 or 15% by volume. AMC performed better than matrix alloys and the commonly used antifriction aluminum alloy AOM 2-1. The dry friction coefficient was 1.5-3 times lower on average, and the volumetric wear rate was 5-9 times lower. An increase in the content of SiC particles in the composite from 5 to 20 vol.%. As a rule, leads to an improvement in the tribotechnical characteristics. The composites obtained have shown a sufficiently high operational suitability for work in friction units with steels both in dry friction and in friction with lubrication.
