A system and associated method are described for depositing high-quality films for providing a nanolayered coating on a three-dimensional surface. The system includes a magnetic array comprising multiple sets of magnets arranged to have Hall-Effect regions that run lengthwise along a sputter target. The system further includes an elongated sputtering electrode material tube surrounding the magnetic array comprising multiple sets of magnets arranged to have Hall-Effect regions that run lengthwise along the sputter target. During operation, the system generates and controls ion flux for direct current high-power impulse magnetron sputtering. During operation logic circuitry issues a control signal to control a kick pulse property of a sustained positive voltage kick pulse taken from the group consisting of: onset delay, amplitude and duration.
