摘　　要： 通过高速电弧喷涂Fe-Al/Cr3C2涂层及其他三种涂层的抗拉和抗热震性能的研究,揭示该涂层的结合机理及提高涂层结合强度的途径。研究发现,添加Cr元素可明显提高涂层的结合强度;涂层的结合方式主要为机械和物理结合;通过提高喷涂温度和速度等可以提高涂层的结合强度。 By high velocity arc sprayed, the tensile and the heat tremble performance of Fe-Al/Cr3C2 coatings and three other coatings were studied, and its bond mechanism and the methods of enhancing bond strength were revealed. The research shows that the bond strength can abviously be enhanced when adding Cr, the main bond type is mechanical and physical bond, the bond strength can be enhanced by increasing the sprayding temperature and velocity.
