【 摘 要 】

This paper deals with individualizing the surface-hardening vacuum carburizing process based on optimal process control. The authors' parametric identification determined that the mathematical model for the vacuum carburizing process requires the use of different mass-transfer coefficients at the stages of saturation and diffusion. The authors analyzed the effect that the optimal surface-hardening process conditions have on the structures and properties of drill-bit steels.
