Oxidation behavior of Ti2AlC MAX phase-based coating on a γ-TiAl alloy TiAl48-2-2 produced by DC magnetron sputtering Surf. Coat. Technol. (IF 5.4) Pub Date : 2024-02-28 Nadine Laska, Radosław Swadźba, Peter Nellessen, Oliver Helle, Ronja Anton
The application of intermetallic γ-TiAl-based alloys is limited by the deterioration in strength and creep resistance as well as reduction in oxidation resistance above 750 °C. The deposition of protective coatings is a promising opportunity to enhance the oxidation resistance or the lifetime with regard to the sustainability by several orders of magnitude. Moreover, additive manufacturing processes

High-speed laser-clad 3533-00 Fe-based cemented carbide coatings on nuclear power valve sealing surface to enhanced wear and corrosion resistance Surf. Coat. Technol. (IF 5.4) Pub Date : 2024-02-28 Jiacheng Fu, Wanyuan Gui, Jingyan Qin, Junpin Lin, Xuechong Ren, Benli Luan
Surfacing welding Co-based alloys coatings is often used to improve the wear and corrosion resistance of nuclear power valve sealing surface. The surfacing welding process, however, resulted in a number of defects, such as porosities, inclusions, and even cracks. Moreover, Co in wear and corrosion debris in a radioactive environment can form Co, which can lead to nuclear contamination and higher maintenance
