| 摘 要： | 摘要：为提高钛管件的耐腐蚀性能及抗冲刷磨损性能，研究了在具有复杂形状钛管件内表面制备氧化铝陶瓷涂层的新方法。先通过爆炸焊接制备了Ti／Al双金属复合管，再将其成形为复杂管件，接着通过微弧氧化将复合管件的铝层进行陶瓷化处理，从而将铝层部分转化为氧化铝层。采用XRD、SEM对氧化铝层的相组成及形貌进行了分析，并对氧化铝层与基体的结合强度、耐腐蚀性能和耐冲刷性能进行了表征。结果表明：涂层主要由γ-A12O3及α—A1203组成，其中γ-A12O3的厚度约为40／μm，α-A1203。的厚度约为10μm；陶瓷涂层与基体结合力达55N，涂层腐蚀电流比钛基体降低5个数量级。另外，氧化铝陶瓷涂层可以有效地防护基体被冲刷。
