Raw data to the article entitled: Effect of tribo-layer developed during turning of Ti–6Al–4V ELI alloy on its low-temperature gas nitriding

The file contains data-set to the article entitled "Effect of tribo-layer developed during turning of Ti–6Al–4V ELI alloy on its low-temperature gas nitriding".The files present results of investigations of tribo-layer developed during turning of Ti–6Al–4V ELI alloy under low-temperature gas nitriding. Roughness and hardness measurements were supplemented by microstructural alaysis using SEM, TEM and XPS.
