    Study on the Preparation and Wear Resistance Properties of Wear-Resistant and Crack-Free Fe-Cr-C-Based Cladding Layer with High Hardness by MU Shuangquan1TONG Yonggang, HUA Manyu, HU Yongle, CAI Zhihai, LIU Jian, HUANG Weiying, WU Pengfei

    Published 2025-07-01
    “…In order to eliminate the cracks produced during the preparation of Fe-Cr-C-based cladding layers by gas metal arc welding and to broaden their application in harsh impact environments,a wear-resistant and crack-free Fe-Cr-C-based cladding layer with high hardness was designed and prepared by optimizing the composition of the Fe-Cr-C-based powder core wire with Nb,Ti,and B elements.The microstructure,microhardness,and wear resistance of the cladding layer were characterized by scanning electron microscopy (SEM),energy dispersive X-ray spectroscopy (EDS),Vickers hardness tester,ultra-depth microscope,and wear testing machine.Results showed that the cladding layer consisted of austenite,eutectic structures and Nb(C,B) hard phases.The Nb(C,B) hard phases were dispersed within the microstructure and acted as pinning agents,resulting in a microhardness of the cladding layer of 900 HV0.2 in the range of 0 to 10 000 μm in depth.Moreover,the Nb(C,B) hard phases,acting as wear-resistant particles during the wear process,prevented micro-cutting and plowing actions of the abrasive particles,thus improving the wear resistance by 76.9%compared to the cladding layer without the addition of Nb,Ti and B elements.The primary wear mechanisms of the cladding layer were abrasive wear and adhesive wear.By optimizing the composition of the Fe-Cr-C powder core wire,the hardness and wear resistance of the cladding layer were effectively enhanced,and the prepared cladding layer was free from cracks.…”
