Liquid Nitriding vs. Gas Nitriding in Case Hardening: What is the Difference?
The next two heat treatment processes are similar. They both use a nitrogen-rich substance to harden soft metal workpieces. But, as the post title implies, the nitrogen arrives in two different states. In one, the nitriding process is applied as a liquid. In the next, the nitrogen coats the workpiece as an all-enveloping gas. Which […]
Controlled Gas Nitriding Process and Its Benefits to Low Carbon Steel
Atmospheric control is a powerful tool in a heat treatment engineer’s metal hardening armoury. For example, by adding gaseous nitrogen to a furnace, the gas nitride hardening effect is initiated. This process sees the gas come into contact with a heated low carbon workpiece. As the surface metal and nitrogen brush against one another, the […]
