This paper investigates the structural, morphological, mechanical and tribological properties of a hard chromium electroplated layer plasma nitrided in a pure nitrogen atmosphere at three different nitrogen pressures: 3.5, 4 and 5 Torr for 90 minutes at 600°C. The results showed that after plasma nitriding at 4 and 5 Torr, a well-defined Cr 2 N layer with a rough and porous morphology was created and the micro-cracks in the hard chromium electroplated layer were almost filled with chromium nitrides. They also showed that increasing the nitrogen pressure from 3.5 to 4 Torr resulted in a significant increase in wear resistance.
