Hypothesis
How does varying the copper content in Ni60CuMo coatings affect their tribological properties?
Conclusion
The coating with 50% Ni-coated Cu showed the best wear resistance and self-lubricating properties.
Supporting Evidence
- The transition layer inhibits crack formation in the coating.
- Increasing Cu content decreases the hardness of the wear-resistant layer.
- The coating with 50% Ni-coated Cu has the best self-lubricating properties.
- At high temperatures, oxidation wear becomes the dominant wear mechanism.
Takeaway
This study looked at how changing the amount of copper in a special coating affects how well it can resist wear and stay slippery.
Methodology
The coatings were fabricated using laser cladding and their properties were analyzed through various tests including hardness and wear resistance.
Limitations
The study did not explore the long-term durability of the coatings under extreme conditions.
