Cementation of hot working steel components by low pressure or vacuum carburation involves fixing the peripheral carbon content by thermodynamic simulation

摘要

Cementation of steel components for hot working, by low pressure or vacuum carburation consists of: (a) fixing the required peripheral carbon content for the carburation temperature by thermodynamic simulation; (b) heating the components under a protective gas atmosphere or vacuum at a temperature in a range from 400 degrees C to the carburation temperature; (c) replacing the protective gas atmosphere or vacuum with a hydrogen atmosphere; (d) carburizing the components and regulating the fixed peripheral carbon by diffusion.
