An overview of planar flow casting of thin metallic glasses and its relation to slot coating of liquid films

Planar flow casting (PFC) is a method that can be used to make thin, long, and wide metallic alloy foils by extruding molten liquid through nozzle slot immediately quenching on moving roller. The rates are high enough amorphous glasses may formed have many desirable properties for variety of applications. This paper reviews how PFC processes were developed, examines the typical operability range PFC, defects commonly form. geometrical similarities between coating process apparent, this highlights differences ranges both processes.
