本研究探讨了潜在的摩擦搅拌表面处理的因瓦合金金属化的Al2O3基板。将具有低热膨胀系数的殷钢箔辊压用作工具，安装在钻孔机上，并在旋转的同时压靠在Al 2 O 3基板上。在空气中，通过这种摩擦搅拌方法，在Al2O3基底上快速形成殷钢膜。工具形状影响膜的形成，并且包裹在箔中的工具在工具与基底之间的接触区域中比简单的金属棒更容易被加热，从而导致更容易的膜形成。
This study examines the potential of a friction stirring surface treatment for the invar alloy metallization of an Al2O3 substrate. An invar foil with a low coefficient of thermal expansion was rolled to use as a tool, mounted on a drilling machine, and pressed against the Al2O3 substrate while being rotated. An invar film was formed rapidly on the Al2O3 substrate by this friction stirring method in air. The tool shape affected film formation, and the tool wrapped in foil was more easily heated in the contact area between the tool and the substrate than simple metal rods, resulting in easier film formation.
