The product obtained by this method is known as cementation steel.
The most common method of forming steel is by the process of cementation.
It seems probable that the Ancients did part gold and silver by cementation.
That it refers to cementation at all hangs by a slender thread, but it seems more nearly this than anything else.
He also gives the method of parting with antimony and sulphur, and by cementation with common salt.
He was familiar with amalgamation, cupellation, the separation of gold and silver by cementation with salt and by nitric acid.
If the cementation be continued too long, the steel acquires a darkish fracture, it is more fusible, and incapable of welding.
After cementation the plate is heated to a certain temperature and is then plunged into an oil bath in order to toughen it.
The progress of the cementation is discovered by drawing a test bar from an aperture in the side.
But steel of cementation, however carefully made, is never quite equable in its texture.
