Oct 15, 2023 · In our previous work, the bias voltage plays an essential role in modulating the microstructure and mechanical properties of (TiVCrNbSiTaBY)N coatings during the radio-frequency (RF) magnetron sputtering [18]. As compared to single ion beam deposition, the film stoichiometry is enhanced in DIBS by mixing oxygen into the working gas (Ar) in the assist ion source [34]. The principle of reactive RF magnetron sputtering is shown Sep 27, 2019 · 2. When a RF potential with a high peak-to-peak voltage is usually coupled to an electrode, an alternating positive-negative voltage appears at the electrode surface. Deposition of non-conductive materials, however, requires a different power delivery system.
