Nitriding potential and cycle time

[eagertknow]

I am making a test cycle matrix for H-13 tool steel case- hardening using gas nitriding process.I need to know four possible values of nitriding potentials and three possible cylce times for a two stage Floe process that can result in suitable hardness values.Can anybody help or guide me to a reference.
