Calculation of the Mixture Flow in a Low-Pressure Carburizing Process [PDF]
Metals, 2019 The right selection of carburizing gas flow rates in the low-pressure carburization process is a key factor in terms of its efficiency. However, a correct calculation of the amount of carburizing gas required for uniform carburization of parts, taking ...

Modeling and Simulation of Vacuum Low Pressure Carburizing Process in Gear Steel [PDF]
Coatings, 2021 A combination of simulation and experimental approaches to optimize the vacuum carburizing process is necessary to replace the costly experimental trial-and-error method in time and resources. In order to accurately predict the microstructure evolution and mechanical properties of the vacuum carburizing process, a multi-field multi-scale coupled model ...

Manganese Volatilization and Its Influence on Low-Pressure Carburizing Process Effects. [PDF]
Materials (Basel)The presented research quantitatively characterizes the depth and fraction of Mn volatilization under LPC conditions for the first time and its influence on surface layer properties. It has been proven that this phenomenon increases with holding time at carburizing temperature and that the intensity of this phenomenon can be limited by using step ...
