Oct 14, 2016 Nitriding and carburizing are the two most common heat treatment practices for surface hardening functional components. The main difference is that in nitriding, into the surface of components. Gas nitriding develops a very hard case in a part at relatively low temperature, without the need for quenching.

Quenching the part only long enough to stabilize surface and core temperatures and then cooling in still air promotes the formation of martensite, the hardest form a steel can take. Forming martensite via other heat treatment processes is possible, but parts encounter significantly more stress in those processes, heightening
February 14, 2017. Quenching metal is one of the critical stages in the heat treatment of a metal part because it's during that process that added hardness is locked in. Nitrogen is the most popular gas quenchant due to its relatively low atomic mass, wide availability and low cost. Helium and argon are also used in gas
Feb 15, 2017 The heating causes changes in the crystalline structure of a metal part's surface; the rapid cooling “freezes” those changes in place and makes the surface harder. The first stage in a quench is Parts made of low-carbon steel and low-hardenability alloys quench better in fast oils. Hot oils are kept at much
"Case hardening allows the surface of the steel to become hard, while the interior retains the part's original properties." Low-carbon steel-like that used in many internal engine components, suspension parts, bushings and other automotive parts-is tough, but also soft and flexible. There are advantages to its ductility, but its
Measurement of a gas quenched C-ring type sample is performed by a Coordinate Measuring Machine. (CMM). Quenching simulation is done with the properties but may increase the product cost by inducing undesirable dimensional changes. The second part deals with the experimental approach for accurately

Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching. It is noteworthy that while the term heat treatment applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and
