摘要

对飞机结构常用的LY12-CZ铝合金在我国海南万宁开展自然暴露试验,分析了自然环境下该型号铝合金腐蚀规律与寿命退化规律。收集整理了该地区的环境数据,通过权重法编制了该地区的地面停放环境谱。在编制的加速环境谱下,对LY12-CZ铝合金进行加速腐蚀试验,通过腐蚀特征等效和寿命退化规律等效的方法确定编制的加速腐蚀环境谱的加速系数。为研究铝合金结构在服役环境下的寿命变化规律提供了理论基础。

Abstract

The fatigue feature of LY12-CZ aluminum alloy under atmospheric corrosion environment is studied and the corrosion law is analyzed. Atmosphere data of the service place is collected and the accelerating environment spectrum is built through weighting analysis. The accelerating experiment of LY12-CZ aluminum alloy is carried out and the accelerating factor of spectrum is calculated by analyzing the effective theory of corrosion and declining rule of fatigue life.
