| A commercial epoxy was modified by adding fluorinated poly (aryl ether ketone) and in turn metal micro powders (Ni, Al, Zn, and Ag) and coated on mild steel. Two curing agents were used; triethylenetetramine (curing temperatures: 30°C and 70°C) and hexamethylenediamine (curing temperature: 80°C). Variation in tribological properties (dynamic friction and wear) and surface energies with varying metal powders and curing agents was evaluated. When cured at 30°C, friction and wear decreased significantly due to phase separation reaction being favored but increased when cured at 70°C and 80°C due to cross linking reaction being favored. There was a significant decrease in surface energies with the addition of modifiers. |
