摘要
分析了导致海军飞机结构腐蚀的主要因素;基于飞机地面停放环境谱,采用某型海军飞机机身背鳍角材在×框连接区模拟件,在试验室条件下分别进行当量5、10、15、20、30 a的加速腐蚀试验,并利用显微镜对试件表面涂层、金属基体材料腐蚀情况进行观察和测量。研究结果表明,结构件当量加速腐蚀与飞机外场服役的腐蚀特征一致,当量加速腐蚀试验时间与外场服役年限相匹配时,基体材料腐蚀程度相当。
The important factor induced corrosion damage of navy aircraft structure was analyzed, Based on the military airport ground environment spectrum, the full scale sample of joint area structure between dorsal fin and frame was tested in laboratory, by use of the accelerated corrosion spectrum, Using XTZ-E microscope, the corrosion characteristic of the coating and base material was inspected and corrosion damage size was measured, after the sample had been accelerated corrosion tested for 5, 10, 15, 20, 30 a respectively, The results showed that the corrosion damage characteristic of the sample in the test was consistent with which in service situations. And damage size was agreeable if accelerated corrosion time matched the service time.
