As a new functional material, amorphous ultra-thin strip is widely used in high-tech fields such as aerospace equipment, power systems, new energy vehicles, medical devices and smart wearables. In industrial production, polished copper roller is used as the solidified base of metal melt, but the high temperature strength of copper is low, and it is easy to wear and fatigue failure under the combined action of molten metal injection force, alternating thermal stress and friction and wear, which becomes the main bottleneck of the preparation of amorphous ultra-thin strip.
