When a metal’s core has worn down, it becomes brittle.
Metal processing plants have been working on rust removal for years, but this is the first time they’ve applied the process to a metal.
Researchers have found that when a metal is processed in the metal processing plant that makes the metal, the rust gets removed.
“Metal-coring processes are known to remove a large percentage of metal rusts on a metal, but there are no proven ways to do it without using a large scale metal processing factory,” says senior research scientist Jurgen Schuetz, a materials scientist at the University of Würzburg, Germany.
Metal-curing methods typically involve drilling holes in the base of the metal and pushing in metal chips that contain the rust to the surface.
This process is used in all types of metalworking processes, from metalworking to milling to manufacturing.
“We wanted to create a process that allows us to remove metal rust on metal surfaces without any of these processes being necessary,” says Schuets.
To find out how to use metal-casting machines, researchers attached two metal-colored pipes to a small metal processing facility.
The pipes are suspended from a platform, and they are covered with a sheet of transparent glass.
“The glass sheet acts like a vacuum,” says researcher Alexander Schoemelius, also a materials researcher at the university.
“When we press the glass against the glass, we can get a very low pressure on the glass and a low amount of heat, and this is called a metal-cell.
This is where the metal gets its surface rust.”
When the glass sheet is pressed against the surface of the glass plate, the heat is transferred to the metal particles inside the glass.
This results in the rust being removed from the metal.
This method is known as metal-cutting.
When a large metal-processing facility is equipped with the machine, the metal is heated with a high temperature until the metal begins to rust.
When the heat wears down the metal plate, it can then be pulled out of the process.
“If you use this method, you can take out all of the rust in the process, and you can also get a higher surface finish than a typical metal-fiber plate,” says study co-author Christian Kupfer.
Researchers hope to eventually apply this process to the production of more metal parts, like parts for aircraft engines.
