Time-Resolved Studies of Plasmas and Afterglows for Material Surface Treatments | Chapter 4 | Plasmas Afterglows with N2 for Surface Treatments synthesis 2024

several types of discharge structures (DC, RF, DBD, magnetron) at different gas pressures from a few mTorr to the atmospheric gas pressure. Pulsed DC plasmas were performed in N₂ and N₂ − H₂ for steel cathode nitriding. Pulsed RF plasmas and afterglows have been studied in Ar and Ar-N₂ with an experimental setup. Both Glow Dielectric Barrier Discharge and Townsend Dielectric Barrier Discharge discharges are homogeneous or diffuse DBDs, free of streamer and microdischarge, and convenient to active polymer It has discussed the effects of reactions between metastable atoms (ArM) and from molecules (N₂, A) in long (10⁻³ s range) and short (10⁻⁶ s range) time afterglows in the excitations of Ar high radiative levels, N₂(C, v = 1) level and NO∗, N₂O∗ bands. Strong emissions of Ti+ and O-atoms when O2 was added to Ar in a short time (10⁻⁶ s range), low Ar pressure (10⁻³Torr) pulsed DC magnetron plasmas which were associated with hard TiO₂ coatings.
