Electrode induction melting gas atomization method to prepare powder metallurgy materials, in the aerospace industry, how to improve their performance and working life?
Electrode induction melting and metal powder preparation are both methods for the preparation of metal materials. They are similar in that they can be used to prepare metallic materials, such as copper, iron, aluminum, magnesium and other metals. The difference lies in the different forms of their raw materials, electrode induction melting mainly uses bulk metal materials, while metal powder preparation usually uses metal powder.
Among the many metal powder preparation methods, electrode induction melting gas atomization method has attracted much attention because of its advantages of high efficiency, high quality and low cost.
Electrode induction melting technology can obtain high-quality, high-purity, high-performance metal materials, so that they have good mechanical properties, corrosion resistance, electrical conductivity, etc. This method is suitable for fields that require the preparation of high-quality metal materials, such as aviation, aerospace, automobile manufacturing, energy, etc.
The metal powder preparation technology has the characteristics of low preparation cost, high material utilization rate, and can prepare multi-component materials, which is suitable for the preparation of complex shapes or subsequent processing and preparation of multi-functional materials. For specific applications, electrode induction melting or metal powder preparation may offer unique advantages that cannot be replaced.
In the field of high-end material preparation, electrode induction melting can prepare high-quality, high-performance metal materials, which are widely used in aviation, aerospace, automotive, energy and other fields.
Electrode induction melting gas atomization method, referred to as EIGA method, is a metal powder preparation method that uses electrode induction heating and high-speed inertial air flow to release metal liquid and vaporize it into metal fine powder. The method mainly consists of two parts: electrode induction melting and gas atomization. The desired metal material is melted by electrode induction melting, and then the metal liquid is sprayed into the high-speed inertial gas stream using gas atomization technology, causing it to splash and quickly cool into a metal powder.
In addition to metal powder, gas atomization electrode induction melting technology is widely used in the aerospace industry, which can manufacture high-performance alloys with high strength, high temperature and high corrosion resistance, multi-metal superalloys, titanium alloys, nickel-based alloys, etc.
The specific process conditions for the preparation of high-performance alloys by gas atomization electrode induction melting technology will affect their performance and lifetime. By selecting the appropriate raw materials, controlling the heating temperature and time, adjusting the gas atomization atmosphere and other process parameters, the preparation process can be effectively optimized and the performance and life of alloy materials can be improved.
By adopting advanced material surface treatment technologies, such as ion implantation, deposition, evaporation, chemical corrosion, etc., the corrosion resistance of alloys prepared by gas atomization electrode induction melting technology can be effectively improved.
Microstructure and nanocrystalline control technology can improve the performance of alloy in terms of corrosion resistance, high temperature strength, high temperature creep and fatigue life. By controlling the heat treatment process of the alloy, the hardness, strength, toughness and other properties of the alloy can be improved and its life can be extended.
In the process of alloy preparation, gas atomization, melting, homogenization, casting and other links, selecting the appropriate alloying element ratio can effectively improve the heat resistance, corrosion resistance and tensile strength of the alloy.
Choosing appropriate protective gases, inert gas, argon, can effectively prevent oxidation reaction in the melting process, reduce oxygen impurity content, control heating temperature and time can effectively control the microstructure of the alloy, so that it can reach the optimal state and improve its performance.
Not only that, high-pressure water cooling technology can also improve the strength of the alloy and the stability of the internal structure, multiple smelting process, scrap aluminum recycling process, pre-oxidation infiltration process and other preparation processes, can effectively optimize the combination, structure and performance of the alloy, improve its life and reliability.
It can be seen that powder metallurgy additive manufacturing technology is an advanced manufacturing technology that manufactures metal parts by stacking and sintering metal powder layer by layer, with high flexibility, high efficiency and high precision. The preparation of metal powder is an important foundation and prerequisite for realizing this technology.
