Characterization of In Situ Synthesized TiC-TiB₂ Reinforced Fe Matrix Wear-Resistant Coating by TIG Arc/Cored-Wires Weld Overlaying Technology

Abstract:

TiC-TiB₂/ Fe matrix composite coatings were in-situ synthesized in the surface of Q235 steel substrate by TIG/cored-wire weld overlaying. The microstructure, micro-hardness and wear resistance of the weld overlay coating were investigated using SEM, XRD, Micro-hardness Tester and Pin-disc Wear Tester respectively. The results showed that the weld overlay coating presented a dense microstructure with defect-free of pore and crack, and better metallurgical bond with the substrate; TiC and TiB₂ particulate distributed dispersively in Fe matrix of the weld overlay coatings. The highest Micro-hardness of the weld overlaying was 1657.58HV, which is 6 times higher than the substrate, and wear resistance are also improved at the room temperature under normal atmosphere conditions.
