Creating Amorphous Metal: The Possibility of Electroplating and Rapid Cooling

In summary, the conversation discusses the potential for creating amorphous metal through electroplating. It is noted that amorphous metal can also be created through rapid cooling of molten metal or using a laser beam to melt metal powder. The question is posed whether electroplating a copper wire with an amorphous alloy could result in the outer layer being amorphous as well. The process of electroplating is described as a crystallisation process controlled by voltage and electric current.

Hello, I've been thinking about if amorphous metal (aka metallic glass) could created by using regular electroplating or if it has to be created by rapid cooling of the metal after molten. There is a method which a thin layer of metal powder is applied to a flat surface where a laser beam melts the metal which then is cooled rapidly. This is followed by layer after layer of metal powder until a three dimensional part is created. So if i would electroplate for example a copper wire with an alloy that can be amorphous until the wire had increased in width, would the electroplated outer layer be amorphous metal? Thanks.

Electroplating is a crystallisation process.
The voltage controls the direction of the reaction and provides the necessary activation energy, while the electric current sets the rate of the reaction. Ions from solution will settle onto existing crystals on the electrode so as to grow those crystals.
 

1. What is amorphous metal?

Amorphous metal, also known as metallic glass, is a type of metal that lacks a crystalline structure. This means that the atoms are arranged randomly, unlike in traditional metals where they are arranged in a specific pattern. This unique structure gives amorphous metals different physical and chemical properties than conventional metals.

2. How is amorphous metal created?

Amorphous metal can be created through a process called rapid cooling, also known as quenching. This involves melting the metal and then cooling it at a very fast rate, typically millions of degrees per second. This rapid cooling prevents the atoms from forming a regular pattern, resulting in an amorphous structure.

3. Can amorphous metal be electroplated?

Yes, amorphous metal can be electroplated like any other metal. The electroplating process involves coating the metal with a thin layer of another metal using an electric current. However, there may be some challenges in achieving a uniform electroplated layer on amorphous metals due to their unique structure.

4. What are the potential applications of amorphous metal?

Amorphous metal has a wide range of potential applications, including in the aerospace, automotive, and electronics industries. Its unique properties, such as high strength and corrosion resistance, make it useful for creating lightweight and durable components. Amorphous metal can also be used for protective coatings, medical devices, and consumer products.

5. What are the advantages of using amorphous metal over traditional metals?

Some of the advantages of amorphous metal include higher strength, increased hardness, and improved corrosion resistance. It also has a lower melting point, making it easier to process and shape into complex forms. Additionally, amorphous metal is more lightweight and can be made into thinner sheets without compromising its strength, making it a desirable material for various applications.
