【摘要】 研究了涂层中光基敏感材料的特性变化与腐蚀的关系,探讨了传感涂层对腐蚀监测的灵敏度。结果发现,所选的两种光基敏感材料传感涂层能有效监测铝合金基体的腐蚀状况。浓度为0.8%、0.5%的光基敏感材料A和B传感涂层,能监测到的平均有效微孔半径分别为44.82μm、56.68μm和93.71μm、83.70μm。更多还原

【Abstract】 Relation between the characteristic change of light-group sensitive materials in coating and corrosion was studied; Sensitivity of light-group sensitive materials sensor for corrosion detection was discussed. As a result, light-group sensitive materials A and B can detect efficiently the corrosion of aluminium alloys substrate. The average radius of microcosmic holes are 44. 82μm, 56. 68 μm and 93. 71 μm, 83. 70 μm, respectively detected by light-group sensitive materials A and B coating whose concentration are 0. 8% , 0. 5% .更多还原
