Microstructural characterization and high temperature oxidation kinetics of Ti-Al-C MAX phase-based coatings deposited by closed hollow cathode PVD on TiAl 48–2-2

This dataset contains the raw and processed experimental data underlying the publication: “Microstructural characterization and high temperature oxidation kinetics of Ti-Al-C MAX phase-based coatings deposited by closed hollow cathode PVD on TiAl 48–2-2”, published in Surface & Coatings Technology (https://doi.org/10.1016/j.surfcoat.2025.132369). The dataset includes data obtained from Closed Hollow Cathode Physical Vapor Deposition (PVD) process monitoring, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Glow Discharge Optical Emission Spectroscopy (GDOES), X-ray Diffraction (XRD), and Thermogravimetric Analysis (TGA). The files comprise raw microscopy data (.dm3, .emi), original SEM micrographs (.tif), elemental mapping exports (.pdf), and numerical datasets in plain text format (.txt) including GDOES depth profiles, XRD diffraction patterns, TGA oxidation curves, and PVD temperature profiles. The data provided here constitute the underlying research data used to generate the figures and quantitative results reported in the publication and enable verification, reproduction, and further analysis of the results. This dataset was generated within the HANACOAT project financed by the National Science Centre, Poland (NCN), project no. 2022/04/Y/ST5/00109 (WEAVE-UNISONO programme).
