What Is Rust And Why Do Metals Rust?
Metal rust, also known as metal corrosion, is a chemical reaction that refers to the process of destruction and deterioration caused by chemical or electrochemical reactions between the metal and its environment. Make the metal an oxidized (ion) state. It is due to its thermodynamic instability, which means that the metal and itself have a higher free energy than some compounds (such as oxides and hydroxides), causing elemental metal compounds to form when the free energy conditions are met.
This will significantly reduce the strength, plasticity, toughness, and other mechanical properties of metal materials, destroy the geometric shape of metal components, deteriorate electrical and optical physical properties, and reduce the equipment’s service life. Under normal conditions, the greater the energy consumed when refining a metal, the faster the metal will corrode.
What Types of Metals will Rust?
Any metal that contains a significant portion of iron, also known as “ferrous” metals, can rust. Metals that will rust include:
Because steel is a mixture of iron and carbon, it will definitely rust. What differentiates steel and stainless steel is the element chromium — chromium forms a shield against rusting, which makes stainless steel more corrosion-resistant. The more chromium content, the better. Regular steel has no such protection against rusting.
Why Does Cast Iron Or Wrought Iron Rust?
Any form of iron can rust when exposed to oxygen and water molecules. Cast iron is a combination of iron, carbon and silicon. Though it’s known for its resistance to wear, it can rust. Wrought iron, on the other hand, contains only trace amounts of carbon. It’s nearly pure iron, so rust is likely to form.
You can protect iron objects from rust by regularly applying paint and removing rust spots with a wire brush. You should also keep iron objects as dry as possible — wipe down cast iron pots and pans with a towel after washing, rather than letting them air-dry. Additionally, wash them right away instead of leaving them to soak. Iron requires much more attention and maintenance than other metals when it comes to avoiding corrosion.
What is Laser Rust Removal Machine?
The laser rust removal machine sends the laser beam generated by the laser generator to the laser rust removal gun via the laser cleaning system, and the laser beam from the laser rust removal gun scans the metal surface for rust cleaning.
Laser rust removal can be thought of as a more advanced level of laser cleaning. Laser rust removal can be accomplished in two ways. One approach is to use clean substrates and surface attachments with very different absorption coefficients at a specific laser energy wavelength. To achieve the purpose of cleaning, the majority of the laser energy irradiated on the surface is absorbed by the surface attachment, which causes it to be heated or evaporated, or rapidly expanded by the vapor flow formed on the surface and driven away from the surface of the object.
The substrate is not damaged, however, because the laser light absorbs very little energy at this wavelength. The key to achieving safe and efficient cleaning is to select the appropriate wavelength and control the laser energy.
The other is a laser rust remover, which is used to clean substrates and surface attachments. The laser energy absorption coefficient is not significantly different, or the substrate is sensitive to the acid vapor produced by coating heat, or the coating produces toxic substances after heating. A high-power, high-repetition-rate pulsed laser is typically used in this method to strike the cleaned surface and convert a portion of the beam into sound waves. The returning portion of the sound wave collides with the underlying hard surface, interfering with the incident sound wave produced by the laser, resulting in a high-energy wave that slightly explodes the coating. The coating is milled, pressed into powder, and vacuumed away without damaging the underlying substrate.
What Is Laser Rust Removal Gun?
A laser rust removal gun is made up of three parts: a gun shell, a galvanometer scanning component, and an iris component. The galvanometer scans the laser generated by the laser generator to form a linear light spot, which is emitted from the square light exit hole of the iris to the object to be cleaned, forming an optical output channel. The adjusting diaphragm can slide along the length of the light-emitting hole on the fixed diaphragm, changing the light-emitting length of the light-emitting hole to make it consistent with the size of the linear light spot, preventing returning light from entering the gun shell during the cleaning process.
The laser rust removal gun has a simple structure, is easy to use, and can process any high-reflective profile. It is adaptable to various types of laser generators. Simultaneously, to avoid pollution, the contact between the optical components in the laser rust cleaning gun and the outside world is closed.
Laser rust removal guns, in addition to being used for handheld laser cleaning, can also be installed on moving mechanical devices (such as robots, manipulators, and CNC machines), with the mechanical device automatically completing the preset motion trajectory. Its advantages include high precision, large-scale operation, and low technical and labor requirements for operators
How Does Laser Rust Removal Machine Work?
Laser rust removal machine transmits the laser beam generated by the laser generator to the laser rust removal gun through the laser cleaning system, and scans the metal surface by the laser beam from the laser rust removal gun for rust cleaning.
Laser rust removal can be understood as a deeper level of laser cleaning. There are two main methods of laser rust removing. One method is to use clean substrates and surface attachments that have very different absorption coefficients at a certain wavelength of laser energy. Most of the laser energy irradiated on the surface is absorbed by the surface attachment, which makes it heated or evaporated, or rapidly expanded by the vapor flow formed on the surface and driven away from the surface of the object to achieve the purpose of cleaning. However, since the laser light absorbs very little energy at this wavelength, the substrate is not damaged. Selecting the appropriate wavelength and controlling the laser energy is the key to achieving safe and efficient cleaning.
The other is a laser rust remover for cleaning substrates and surface attachments. The laser energy absorption coefficient is not much different, or the substrate is sensitive to the acid vapor formed by the coating heat, or the coating will produce toxic substances after heating. This method typically uses a high-power, high-repetition-rate pulsed laser to strike the cleaned surface and convert part of the beam into sound waves. The returning portion of the sound wave hits the underlying hard surface, interfering with the incident sound wave produced by the laser, producing a high-energy wave that causes the coating to explode slightly. The coating is milled, pressed into powder, and then removed with a vacuum pump without damaging the underlying substrate.

How Much Does Laser Rust Removal Machine Cost?
The price of a laser rush removal machine is different from the pricing methods of traditional cleaning such as detergents. Compared with the attributes of cleaning agents as consumables, laser rust cleaning machines can be used repeatedly. As a laser equipment, its price mainly depends on different configurations. For example, if a laser generator with higher power is used, the price will definitely be higher.
The price of 1000W portable laser rust remover starts from $8800. The price range of 1500W handheld laser rust removing machine is from $9800. The minimum cost of 2000W high power laser rust removal machine is $12,800. Of course, the price of an automatic laser rust cleaning machine with CNC controller or robot will be higher. Even if the configuration is similar, the costs from different manufacturers are not the same. Because the cost not only involves configuration, but also includes shipping, brand, after-sales service, and other factors.
