摘　　要： 采用添加增强相的Fe-Al粉芯丝材和高速电弧喷涂技术(HVAS)原位合成了复合涂层.对添加了不同增强相的涂层组织和性能进行了研究,分析了陶瓷增强相的选择对涂层物理和化学性能的影响.结果表明,对高速电弧喷涂Fe-Al/WC涂层和Fe-Al/Cr3C2涂层的性能比较显示,在丝材中添加Cr3C2增强相对比添加WC增强相,可以显著提高铁铝涂层的耐冲蚀以及耐腐蚀性能,明显提高涂层的常温耐磨损性能,并有效提高涂层的结合强度. Coatings were in-situ synthesized by using cored wires Fe-Al that added ceramic reinforcements and high velocity arc spraying (HVAS) technology. The structure and properties of coatings that added different reinforcements were investigated. The influence of the selection of ceramic reinforcements to the physics and chemical character of coating was analyzed. The results show that, by the contrasts between HVAS Fe-Al/WC coatings and Fe-Al/Cr3C2 coatings, the adding of reinforcements Cr3C2 can elevate the erosion and corrosion properties of coatings, it can also elevate room temperature wear properties of coatings, and can increase the bonding strength of coatings effectively.
