摘要

摘要: 以Fe-Cr-C合金粉末為原料,采用反應等離子熔覆技術,在45^#鋼表面制得以原位生成初生相(Cr,Fe)₇C₃為增強相的新型陶瓷復合材料涂層.利用SEM,XRD,EDS和顯微硬度計等分析了涂層的顯微組織和硬度,分別在室溫干滑動磨損及高溫滑動磨損條件下測試了涂層的耐磨性,并討論了其磨損機理.結果表明,涂層組織包括(Cr,Fe)₇C₃增強相和γ-Fe固溶體與少量(Cr,Fe)₇C₃構成的共晶,該涂層在室溫干滑動磨損和高溫滑動磨損條件下均具有優異的耐磨性.

Abstract: An in-situ reinforcing phase (Cr,Fe)₇C₃ ceramal composite coating was fabricated on the substrate of a 0.45% carbon steel using Fe-Cr-C elemental powder blending by reactive plasma clad process. The microstructure and micro-hardness of the coating were evaluated by SEM, XRD, EDS and micro-hardness instrument, the room temperature and high temperature wear properties were evaluated under dry sliding wear test conditions, and the wear mechanism was discussed. The results indicated that the reactive plasma clad ceramal composite coating has a rapidly solidified microstructure consisting of primary (Cr,Fe)₇C₃ and (Cr,Fe)₇C₃/γ-Fe eutectics, with excellent wear properties under both room-temperature and high-temperature sliding wear test conditions.
