Troubleshooting Nitriding Process Problems – Part 2

The nitriding process improves the life expectancy of machine parts, so reducing the consumption of steel and energy and, as a result, the cost of the entire manufacturing process. For this reason, it may be considered both economically and ecologically beneficial. Economical and ecological advantages will at the same time characterise a process in which […]

Troubleshooting Nitriding Process Problems – Part 1

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 treatments are concerned. Below are […]

Process and Applications of Black Oxide

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 corrosion resistance, enhance appearance, and […]

What is Carburization in Heat Treatment?

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 items to carbon atoms.  The […]

How a Heat Treatment Modifies Metal Properties

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 depends upon the size of […]

The Hot-Temperature vs. Mid-Temperature Black Oxide Process: What Are the Differences?

Black oxide is a conversion coating that is suitable for ferrous metals along with copper-based alloys, copper, zinc, stainless steel, silver solder and powdered metals. It accomplishes this through a chemical reaction since it is made of caustic oxidisers and additives. Also, it gives items a lustrous, black appearance and provides some corrosion protection. On […]

Common Issues with Induction Hardening

The process of induction hardening is for the purpose of hardening the surface of components made from steel or other carbon-alloy metals. Components or parts include a wide assortment of axles, pins, rollers and shafts. As much as 15-mm hardness depths can be achieved. Parts are placed in a special furnace that utilizes a coil […]

Controlling Furnace Atmosphere in Heat Treatment

A second heat treatment effector exists in an industrial furnace, one that’s sometimes forgotten by the average layperson. Besides the heat source, the gas-fuelled or electrically energized thermal energy flowing evenly around a subject workpiece, there’s the atmosphere inside that sealed chamber to consider. Sometimes, the atmosphere is totally taken out of the heat treatment […]
