Vacuum carburizing—process optimization

Journal of Materials Processing Technology, 2005
Abstract An increased interest in vacuum carburizing concept is being observed in the last years all around the world as a result of the progress in designing of modern furnaces for thermo-chemical treatment under low pressure and of better knowledge of physico-chemistry of these processes.

In Situ Monitoring of Vacuum Carburizing

Materials and Manufacturing Processes, 2009
The present article describes development and testing of a new measurement method that enables nondestructive and in situ monitoring of a vacuum carburizing process. The principle of the method is based on monitoring the carbon diffusion during vacuum carburizing by the in-situ measurement of electrical resistance changes in the carburizing sample ...

Modeling of vacuum pulse carburizing of steel

Surface and Coatings Technology, 2014
Abstract A review on carburization process modeling is presented and a new model for carbon diffusion in steel subjected to heat treatment by vacuum pulse carburizing is proposed. Such a process is carried out by repeating consecutively a carburizing stage (the boost), when the carburizing gas is supplied into a carburizing chamber, and the diffusion

Influence of the Temperature of Vacuum Carburizing on the Thickness of the Carburized Layer and Properties of Steel Parts

Metal Science and Heat Treatment, 2020
The properties of steel parts after carburizing in low-pressure acetylene are studied. The thickness of the carburized layer, its hardness, the microstructure, and the hardness of the core are determined after carburizing at 900 – 960°C with simultaneous shortening of the process from 104 to 44 min. The data obtained for the diffusion of carbon make it
