摘要：为探讨荧光元素在腐蚀监测领域的应用,围绕Ce掺杂YAG(Y_3Al_5O_(12))粉末和涂层的制备,探讨硝酸腐蚀对涂层发光性能的影响。结果表明高温固相法形成的YAG:Ce粉末主要为YAG相,等离子喷涂涂层则以YAG和YAP(YAlO_3)相为主。经过在硝酸中腐蚀不同的时间后,涂层的孔隙率和衍射峰的强度均增加。同时,衍射峰的主峰位置发生移动。涂层的发光强度随腐蚀时间的增加呈现先增加再降低之后增大的波动趋势。涂层的发光强度受其孔隙率、衍射峰位置和强度等多种因素的影响。
To explore the application of fluorescence elements in the field of corrosion monitoring, Ce doped YAG （Y3A15012） powder and coatings were prepared. The effect of immersion duration in nitric acid on the luminescent intensity was studied. The results show that the YAG：Ce powder is mainly composed of YAG phase, The plasma sprayed coatings are dominated by YAG and YAP （YA103）. The porosity and diffraction peak intensity of YAG：Ce coatings increase with the immersion duration in nitric acid. Meanwhile, the diffraction peak position moves for the coatings after they are immersed in the acid. The luminescent intensity of coatings increases firstly, then decreases, and finally increases with the increment of immersion duration. The luminescent intensity of coatings is influenced by the porosity, crystallinity and phase composition of coatings, etc
