Hypothesis
How does varying the ZrB2 content affect the properties of copper matrix composites?
Conclusion
Increasing ZrB2 content improves mechanical properties but decreases density, porosity, and corrosion resistance in copper matrix composites.
Supporting Evidence
- ZrB2 improves hardness and wear resistance in copper composites.
- Relative density decreases from 98% to 90% with increasing ZrB2 content.
- Composites with higher ZrB2 content show lower friction coefficients.
Takeaway
Adding ZrB2 to copper makes it stronger but also makes it less dense and more prone to rusting.
Methodology
The study used ball-milling and spark plasma sintering to create Cu-ZrB2 composites and tested their physical, mechanical, and corrosion properties.
Limitations
The corrosion resistance of the composites was significantly reduced in acidic environments.
