In the original online version of this article there were typographical errors in point 2 of the Conclusions section. Following is the corrected text:

(2) The nitride compound existed in two phases, the ε phase and the γ′ phase. In the initial nitriding process, the γ′ phase was 5.8 pct due to a high Kn of more than 10, while the fraction of the ε phase was 94.2 pct. Afterward, as the process progressed at a Kn of 1.0, the fraction of the γ′ phase increased to 87.4 pct, and the fraction of the ε phase decreased to 12.6 pct.

The original article was corrected.
