Corrosion-resistant plasma-sprayed Ni-Al composite coatings using graphene oxide fillers

NiAl powders were enhanced by graphene oxide dispersion in water, which was then coated onto A36 steel using plasma spray. The provided data includes X-ray diffraction analysis and micro-Raman spectroscopy analysis of the enhanced powders and the sprayed coatings. The data related to Potentiodynamic polarization testing and electrochemical impedance spectroscopy are also provided to showcase the corrosion performance of the coatings after 1 hour and after 30 days of exposure to a 3.5% NaCl solution.

本数据集以水中氧化石墨烯分散液对镍铝（NiAl）粉末进行增强改性，随后通过等离子喷涂工艺将改性后的粉末涂覆于A36钢基材表面。所提供的数据涵盖增强后粉末与喷涂涂层的X射线衍射（X-ray diffraction）分析、微拉曼光谱（micro-Raman spectroscopy）分析；同时还包含动电位极化测试（Potentiodynamic polarization testing）与电化学阻抗谱（electrochemical impedance spectroscopy）相关数据，用于表征涂层在3.5%氯化钠溶液中分别暴露1小时与30天后的腐蚀性能。
