Carburizing - Wikipedia
Carburizing, or carburising, is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide.
Mechanism of high temperature reduction on iron carbide …
2022年1月5日 · High temperature reduction is a feasible measure to promote the carburization efficiency of siderite pellet. The value of η significantly increases from 20.05 (without reduction) to 36.59 (reducing for 120 min) in the condition of reducing at …
Carburization - an overview | ScienceDirect Topics
Carburizing is a thermo-chemical process in which iron or steel absorbs carbon from a carbon-bearing material at processing temperatures between 850–1000°C, with the intent of hardening the metal (ASM, 2014).
Carburising Explained – How It Works, Benefits & Types
2023年7月27日 · Carburising is a heat treatment process that improves mechanical properties such as hardness by adding carbon to a metal’s surface. As the carbon addition is limited to the surface, the process forms a hard case around the part along its surface area. Thus, the carburising process is a type of case-hardening process.

Carburizing is a thermo-chemical process in which iron or steel absorbs carbon from a carbon-bearing material at processing temperatures between 850–1000°C, with the intent of hardening the metal (ASM, 2014).
Introduction to Carburizing and Carbonitriding
Carburization is the process of intentionally increasing the carbon content of a steel surface so that a hardened case can be produced by martensitic transformation during quenching. Like carburizing, carbonitriding involves heating above the upper critical temperature to …
Carburizing: Types, Principle, Applications - Heat Treatment Masters
2023年8月29日 · Carburizing, also known as Case Hardening, is a heat treatment process that improves the surface properties of steel components. By diffusing carbon into the surface, carburizing creates a hardened case while maintaining the toughness and strength of the core.
Carburizing and Carbonitriding - SpringerLink
Carburizing is a heat treatment in which the carbon content of the surface of a low-carbon steel is increased through a diffusion process by exposure to an appropriate atmosphere in the austenitic condition, generally in the range of 850–950°C.
Sustainable carburization of low carbon steel using organic …
2023年12月1日 · The control of carbon dioxide (CO 2) is critical to gas carburization as high CO 2 signals the risk of grain-boundary oxidation, which weakens the carburized surface [65]. Internal oxidation occurs as a result of the diffusion of oxygen (O 2) into the grain boundary of the steel being carburized.
Laboratory Carburization of Direct-Reduced Iron in CH
2016年2月25日 · Direct-reduced iron (DRI) is used as a low-residual feed material for electric furnace steelmaking, and a source of metallic iron in blast furnace ironmaking. DRI contains carbon as a result of carburization reactions in the lower part of gas-based direct-reduction shafts; the carbon forms by decomposition of methane (CH 4 ).
