Abstract

The effect of Planar Flow Casting (PFC) parameters on dimensional specifications of amorphous soft magnetic Co68.15Fe4.35Si12.5B15 foils was investigated. PFC experiments were carried out under an argon atmosphere and the relationship between the main processing parameters, such as linear wheel velocity, nozzle-wheel gap distance and ejection pressure, with the resulting foil thickness was studied. It was found that there are linear relationships between the foil thickness and reciprocal of wheel speed, fourth root of nozzle-wheel gap and square root of ejection pressure. It was also shown that obtained results are in good agreement with the equation proposed by Fiedler.
