Material wettability improvement device and method based on multi-field coupling

Abstract

The invention provides a material wettability improvement device and method based on multi-field coupling. The material wettability improvement device comprises an operation platform, a vacuum furnace stored on the operation platform, a high-voltage power supply control box, an ultrasonic auxiliary device, an electric field auxiliary device and a magnetic field auxiliary device. A rack on one side of the vacuum furnace is provided with a guide rail stand column. The upper end of the guide rail stand column is provided with a movable cross beam. An ultrasonic transducer is fixed to the cross beam. An ultrasonic variable-pressure rod stretches into the vacuum furnace through a corrugated pipe. The electric field auxiliary device is arranged below the ultrasonic variable-pressure rod. A sample is stored on an insulating ceramic plate and positioned through a stop block. The inner side of the vacuum furnace is further provided with a magnetic field power coil which generates a variable magnetic field after being applied with current. By adoption of the material wettability improvement device and method, the sample can be wetted under mutual assistance of an ultrasonic vibration load, an electric field and the magnetic field, and the problems that existing additionally arranged auxiliary equipment is simplex in applying mode, the ultrasonic applying mode is large in power loss, and simplex assistance is unobvious in sample wettability improvement effect are solved.

Description

technical field

[0001] The invention relates to a material wetting device, which belongs to the technical field of material performance testing, and mainly relates to a device and method for improving material wettability based on multi-field coupling. Background technique

[0002] Wettability is not only a key factor for evaluating the quality of brazed joints, but also a key indicator for evaluating the interfacial bonding of composite materials. Good wettability is the prerequisite for obtaining high-reliability brazing joints. The traditional way to improve the wettability of solder is mainly through the method of adding flux, using the chemical reaction of flux to remove the oxide film on the surface of the material, so as to achieve The purpose of reducing the surface tension of the material, but the flux is corrosive, and the performance of the welded joint will be greatly reduced during the service of the weldment; in terms of composite materials, if the reinforcemen...
