摘要
采用超音速火焰喷涂（High-Velocity-Air-Fuel，HVAF）技术在7075高强铝合金上制备了WCIOC04Cr涂层，用XRD和SEM分别对涂层的相组成和显微结构进行了分析，阐述了涂层的结合机理，并研究了拉伸对偶件的弹性模量对测试涂层结合强度的影响．结果表明，采用HVAF技术，可在高强铝合金基体上获得致密、结合强度较高的WCoCoCr涂层．
In the experiment, WC-CoCr coating on 7075 high strength aluminum alloy substrate was prepared by High-Velocity-Air-Fuel （HVAF）. The phase and microstructure of the coating was investigated by XRD and SEM, and the bonding mechanism was discussed in detail. In addition, the influences of elastic modulus of parts on the characterizations of bond strength of coatings were also analyzed. The result showed that the dense WC-CoCr coating with high bonding strength can be manufactured on the substrate of high strength aluminum alloy by HVAF process.
