| 摘 要： | 利用活性燃烧高速燃气(AC-HVAF)喷涂技术在7075高强铝合金基体上制备了WC-10C04Cr和WC-14Co涂层,并利用SEM、EDS、XRD、电化学测试以及中性盐雾(NaCl)腐蚀试验等方法分析了涂层的物相、微观组织、耐腐蚀性能和腐蚀产物形貌.结果表明:所制备的WC涂层均未出现明显的脱碳现象,都很致密,孔隙率低于1%且与基体结合较好;WC涂层的腐蚀电位明显高于7075铝合金基体的,而涂层中hA.铬元素后进一步提高了涂层的腐蚀电位;WC-10C04Cr涂层在600 h中性盐雾试验中的耐腐蚀性能好于WC-14Co涂层的.

| Abstract: | WC-10Co4Cr and WC-14Co coatings were prepared using activated combustion high velocity air fuel(AC-HVAF) spraying technology on 7075 high strength aluminum alloy substrate.The microstructure, corrosion resistance and corrosion morphology were investigated by means of SEM,EDS,XRD,electrochemical testing and neutral salt spray testing.The results show that WC coatings presented no obvious decarburization.The coatings were dense and the porosity was below 1%.The binding with the substrate was fairly good.The c... |
