Abstract

A carbon-aluminum interface wetting and structure regulating and controlling device and method under ultrasonic field coupling are provided. The device comprises a vacuum cover, an object stage, a crucible, a radiator, a coupler, a liquid adding device, a heating resistance and a thermocouple; the radiator is connected with the coupler and an ultrasonic power supply; the object stage is assembled together with a thread screw rod and a drive motor; the vacuum cover is communicated with an atmosphere control device, an inert gas system and a vacuum pump system through valves. The method comprises the steps: placing a carbon substrate in the crucible; adjusting an atmosphere in the vacuum cover; adding a metal melt into the crucible, and adjusting the height of the object stage; vacuumizing; introducing an inert gas to the normal pressure; heating through the heating resistance; controlling the carbon substrate to rotate so as to make a metal melt oxide film ruptured; and carrying out ultrasonic coupling of the metal melt. The device and the method are integrated with acoustic streaming and cavitation of an ultrasonic field, and obtain ideal interface structure control conditions through optimization of acoustic field collaborative conditions and optimization of wetting and interface reaction conditions.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a carbon-aluminum interface wetting and structure regulation device and method under ultrasonic field coupling. Background technique

[0002] Liquid / solid wetting and interfacial behavior is a common physical and chemical phenomenon in the process of material preparation and chemical synthesis. It is a key technical link in materials engineering, which largely determines the possibility of material preparation, the final tissue performance, and production efficiency.

[0003] For example: in the in-situ synthesis process of AlTiC grain refiner and TiC particle reinforced Al-based composite material, due to the poor wettability between C (Carbon) and Al melt, C powder often adsorbs impurities such as gas, which is easy to generate hydrogen bonded and aggregated into clusters, making it difficult for the Al melt to infiltrate into the interior of the C powder for rea...
