  • 反應火焰噴涂TiC-Fe涂層的耐磨性能

    Wear Resistance of Reactive-flame-sprayed TiC-Fe Coatings

    • 摘要: 研究以鈦鐵、石墨和純鐵粉為原料,用反應火焰噴涂技術制備Tic-Fe金屬陶瓷涂層的耐磨性能.結果表明,涂層中富TiC和貧TiC片層的顯微硬度分別達11.9~13.7GPa和3.3~6.0 GPa.在SRV磨損試驗機上經20 min的干磨擦試驗表明,反應火焰噴涂TiC-Fe涂層具有良好的耐磨性能,大約是常規火焰噴涂WC-Ni45金屬陶瓷涂層的5倍.綜合磨痕的輪廓曲線及其SEM形貌發現,其磨損機理主要是粘著磨損,但也有少量細小的硬質相剝落.

       

      Abstract: The wear resistance of TIC-Fe cermet coating prepaid by reactive flame spray of ferrotitanimu, graphic and iron powders was sutdied. It was revealed that the microhardness of TiC-rich and TiC-poor layer within the TiC-Fe composite coatings is 11.9-13.7 GPa and 3.3-6.0 GPa, respectively. A dry wear test showed that their wear resistance is five times higher than WC-Ni45 cermet coatings obtained by traditional process. The major wear mechanisms are surface adhesion and a little stripping of TiC.
