https://doi.org/10.1007/s00170-021-06710-6

The original article contained a mistake.

The correct bibliographic data for Reference 33 are:

Psyllaki P, Kefalonikas G, Pantazopoulos G, Antoniou S, Sideris J (2003) Microstructure and tribological behaviour of liquid nitrocarburised tool steels. Surf Coat Technol. 162(1):67–78. https://doi.org/10.1016/S0257-8972(02)00566-2

Instead of:

Psyllaki P, Kefalonikas G, Pantazopoulos G, Antoniou S, Sideris J (2002) Microstructure and tribological behaviour of liquid nitrocarburised tool steels. Surf Coat Technol:67–78.

The original article has been corrected.
