Hypothesis
The study investigates the tribological properties of polytetrafluoroethylene-reinforced fluorocarbon composite coatings under various working conditions.
Conclusion
The optimal formulation for the coatings significantly reduced the coefficient of friction compared to pure FEVE coatings.
Supporting Evidence
- The friction coefficients of the FEVE/50 μm-PTFE coating under dry friction and water lubrication were 0.067 and 0.062, which were 86% and 92% lower than those of the pure FEVE coating.
- The friction coefficient of the FEVE/5 μm-PTFE coatings in oil lubrication was 0.055, which was 56% lower than that of the pure FEVE coating.
- The optimal combination for coating preparation was determined based on orthogonal tests.
Takeaway
This study shows how mixing certain materials can make coatings that help machines work better by reducing friction.
Methodology
The coatings were prepared using spraying and room-temperature curing, and their properties were tested under different lubrication conditions.
