چکیده انگلیسی
A molybdenum alloy (TZM: 0.50â¯wt% titanium, 0.08â¯wt% zirconium and 0.02â¯wt% carbon with balanced molybdenum) was used to investigate its response to plasma nitriding in terms of layer formation and hardening at temperatures between 500 and 760â¯Â°C using various times. A thin hard nitride case plus a shallow diffusion zone was formed after plasma nitriding. The thickness of nitride layer increased with the treatment temperature and time. The nitrided surface of molybdenum alloy had a low coefficient of friction against the Al2O3 counterpart ball at ambient atmosphere and elevated temperatures, and the wear resistance of the surface was greatly improved. Molybdenum had a tendency to react with nitrogen to form a mixed nitride phases at the tested temperature range, and the TZM alloy had an activation energy of 330â¯kJ/mol.
