Problems solved by technology

These methods are all through the transfer of media, depositing a film on another object. During this transfer process, no oxides can be guaranteed; because different media will cause uneven films, the quality of the generated metal films is not good. Pure, easy to produce defects; in addition, most of these preparation methods have the disadvantages of cumbersome process, low preparation efficiency, many control factors, easy consumption of materials, and easy generation of harmful gases.

Abstract

The invention discloses a device and method for preparing a metal film through area expansion in a vacuum environment. The device comprises a vacuum furnace, wherein an experiment table is arranged inthe furnace and fixed on a manipulator device; and a pressurizing device is arranged above the experiment table, a reflecting plane mirror and a condensing convex lens are arranged on the pressurizing device, and a high-melting-point metal ring is arranged on the surface of the experiment table. According to the method, the characteristic that no air exists in the vacuum environment is utilized,a high-melting-point alloy wire is adopted to define a circle with the controllable area, one low-melting-point metal block is placed in the center of the metal ring, sunlight is gathered to melt thelow-melting-point metal block into molten metal, and the molten metal adheres to the metal wire through surface tension. Due to the fact that the vacuum environment has no heat conduction and heat convection, heat exchange can only be carried out through heat radiation, the molten metal is slow in heat dissipation and not prone to solidify, and after the temperature rises to be slightly higher than the melting point of the low-melting-point metal block, the molten metal adheres to the alloy wire due to the surface tension and gradually expands into a film along with the increase of the area ofthe metal ring; and the method is combined with the physical change of medium-free heat transfer process, the material utilization rate is high, the preparation process is simple and efficient, and environment-protecting and energy-saving, and the formed film is high in surface quality and excellent in performance.
