Abstract
For improving the microstructure and tribological properties of the deposited layer, different contents of Y2O3 are added to Fe-based deposited layers reinforced by NbC particles generated in situ, respectively. The main phases of Fe-based deposited layers reinforced by in situ-generated NbC particles with different contents of Y2O3 are revealed by X-ray diffraction, and the microstructure of the deposited layers is characterized by scanning electron microscopy and energy-dispersive spectroscopy. The influence mechanisms of Y2O3 content on the wear form and tribological properties of Fe-based deposited layer reinforced by in situ-generated NbC particles are analyzed, and the wear mechanism of Fe-based deposited layers reinforced by in situ-generated NbC particles with different contents of Y2O3 is revealed. The results show that the addition of Y2O3 promotes the generation of Cr7C3 and inhibits the generation of Cr23C6. With the increase of Y2O3 content, the size and morphology of in situ-generated NbC particles in Fe-based deposited layer change. When the content of Y2O3 is 2 wt%, a large number of fine petal-shaped NbC particles are precipitated, and tribological properties of the deposited layer are excellent. The research results provide theoretical basis and data support for further application of direct energy deposition.
期刊介绍：
steel research international is a journal providing a forum for the publication of high-quality manuscripts in areas ranging from process metallurgy and metal forming to materials engineering as well as process control and testing. The emphasis is on steel and on materials involved in steelmaking and the processing of steel, such as refractories and slags.
steel research international welcomes manuscripts describing basic scientific research as well as industrial research. The journal received a further increased, record-high Impact Factor of 1.522 (2018 Journal Impact Factor, Journal Citation Reports (Clarivate Analytics, 2019)).
The journal was formerly well known as "Archiv für das Eisenhüttenwesen" and "steel research"; with effect from January 1, 2006, the former "Scandinavian Journal of Metallurgy" merged with Steel Research International.
Hot Topics:
-Steels for Automotive Applications
-High-strength Steels
-Sustainable steelmaking
-Interstitially Alloyed Steels
-Electromagnetic Processing of Metals
-High Speed Forming
