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 a nozzle slot and immediately quenching on a moving roller. The quenching rates are high enough that amorphous metallic glasses may be formed that have many desirable properties for a wide variety of applications. This paper reviews how PFC processes were developed, examines the typical operability range of PFC, and reviews the defects that commonly form. The geometrical similarities between PFC and slot coating process are apparent, and this paper highlights differences between the operability ranges of both processes.

薄金属玻璃平面流延及其与液膜槽涂关系的概述

平面流铸 (PFC) 是一种通过喷嘴槽挤出熔融液体并立即在移动辊上淬火来制造薄、长和宽的金属合金箔的方法。淬火速率足够高以致可以形成具有多种应用所需的许多特性的非晶金属玻璃。本文回顾了 PFC 流程是如何开发的，检查了 PFC 的典型可操作范围，并回顾了通常形成的缺陷。PFC 和狭缝涂层工艺之间的几何相似性很明显，本文重点介绍了两种工艺的可操作范围之间的差异。
