Carburizing an iron material, especially steel, comprises performing carburization on the basis of a calculated carbon diffusion coefficient

摘要

Carburizing an iron material comprises carburizing a test piece, determining the chemical composition of the material, calculating an alloying factor for correcting the carbon level, measuring the carbon level and carburization rate over time, measuring the variation in carbon concentration with depth, calculating the carbon diffusion coefficient using an equation based on Fick's law, and carburizing the iron material on the basis of the calculated diffusion constant.
