The nitriding process is perhaps one of the most misunderstood thermo-chemical surface treatment processes that are practiced today. So the process is not as old as, for example carburising. However, it is perhaps (as far as chemistry is concerned) one of the most simple of all of the thermo-chemical surface […]
The process of forming black iron oxide to ferrous metals and other types of materials is often called black oxide. The black oxide process is a chemical conversion coating for ferrous materials, stainless steel, copper and copper-based alloys, zinc, powdered metals, and silver solder. This process is done to add […]
Case hardening is a process of reinforcing the surface of some types of soft metal, making them more durable and tough. This process forms a thin layer of durable metal coating that allows the metal underneath to remain soft. One type of case hardening is carburization, which involves introducing steel […]
A heat treatment does far more than just change the physical appearance of metals. It also can modify the properties of them to reach the intended goal. This type of treatment involves heating and cooling the metals at the right temperatures to alter their microstructure. How long the treatment requires […]
Various properties of metals experience change when they go through a heat treatment. Some changes make the metals more resilient or resistant while others allow them to be reshaped. Even though modern technology has created new methods for this type of treatment, blacksmiths many years ago used to accomplish similar […]
