Description

technical field [0001] The invention relates to a metal material alloying and composite material preparation device and a use method thereof, in particular to a metal suspension ultrasonic field strong coupling suspension driving device and a use method thereof. Background technique [0002] Although pure metals have been applied in industry to a certain extent, due to their limitations in performance, they cannot meet the requirements of various applications. Alloying is the main way to improve and enhance their performance; Hardness, high modulus of elasticity, excellent thermal stability and matrix high toughness, plasticity, good thermal conductivity and electrical conductivity, is a very important engineering structural material. [0003] The main methods of alloying metal materials are: direct addition of alloy components, addition of intermediate alloys, alloy additives, and reaction synthesis. In the direct addition method of alloy components and the preparation pro...

Problems solved by technology

[0010] The current ultrasonic field coupling method for metal suspensions usually uses an ultrasonic generator and a coupling radiation block to directly couple the ultrasonic field wave energy to the metal liquid, form a secondary sound wave through the emission plate, and superimpose with the primary sound wave to form a static standing wave field. The sound pressure difference drives the suspended phase to gather at the static sound pressure node, but because the standing wave field is in a static state, there are problems of low renewal intensity of the reaction interface and low surface reactivity. continuous
