| Abstract: | The Dynamic Chemical Plating (DCP) technique allows production of 2-μm copper films containing particles of graphite or PTFE
in 18 and 15 min, respectively, at ambient temperature. DCP yields composites with particle-incorporation fractions of 12%
for graphite micro-particles and 22% for PTFE nano-particles. The composite films show excellent tribological properties,
acting as self-lubricating coatings with friction coefficients as low as 0.18. |
