TL;DR
This study examines how adding SiC and graphite to copper affects the material's structure, wear resistance, and oxidation properties.
Contribution
The paper introduces a novel analysis of how SiC and graphite reinforcement affects the thermal and mechanical properties of copper composites.
Findings
Composites showed increased structural hardness and wear resistance with SiC and graphite reinforcement.
Bare SiC significantly improved oxidation resistance compared to pure copper.
Graphite-SiC composites performed better at lower temperatures, while lean SiC composites excelled at higher temperatures.
Abstract
Using the powder metallurgy process, this study focused on the impact of varying concentrations of SiC and graphite additions on microstructural, tribomechanical, and thermophysical properties. The resulting composites had a high relative density (>90%). The reinforcement particles exhibited a homogeneous distribution in the copper matrix. No compound developed between the reinforcing and copper phases. There was good interfacial bonding between the graphite and SiC structures. The composites’ overall structural hardness increased by 1.04 to 1.25 times. From 1.13 to 1.40 times, the empirical elasticity modulus increased. With SiC and graphite reinforcement, wear resistance was increased 10-fold to 12-fold for the wear tests. Lean graphite reduced friction by around 2.4 times. The samples that were chosen based on their tribomechanical characteristics underwent oxidation testing. The…
