Thickness of compound layer and nitrogen diffusion layer. The first column (a-1, b-1, c-1) represents formed layer thickness, while the second column (a-2, b-2, c-2) represents hardness profiles. From top to bottom, the sequence of the rows is process temperature, process gas ratio, and process pressure.
