- •
The Cup/Fe composite coatings are fabricated via PTA alloying process.
- •
PTA heat input affects the synthesis of the composite coatings.
- •
The Cu-rich particles are formed in the coatings due to liquid phase separation.
- •
Cu film is formed during friction process, which can act as a lubricant.
