摘要:

本文介紹了艦載機點蝕、絲狀腐蝕、晶間腐蝕、應力腐蝕和氫脆5種常見的腐蝕失效模式及其形成機理、失效現象與特征、影響因素等，列舉了與設計、制造工藝、材料等因素相關的導致飛機構件腐蝕失效的典型案例，并根據案例的失效原因提出艦載機腐蝕失效的預防與改進措施，以及在設計、制造工藝和選材方面的一些建議。結果表明，飛機的腐蝕控制是一項系統工程，設計中需要充分考慮對導致腐蝕的因素進行有效控制，并注意細節防腐設計；在選用合理的防腐工藝措施的同時，工藝和材料選擇與環境之間，工藝與材料之間在防腐方面均應匹配。

Abstract:

Pitting, filiform corrosion, intergranular corrosion andhydrogen embrittlement are the common corrosion failure modes in the carrier-based aircraft. The formation mechanisms, failure phenomena,failure characteristicsand influencing factors of these five failure modes are introduced in this paper. Several typical cases of corrosion failure which induced by design, manufacturing processes, materialsand otherfactors are presented respectively. The prevention and improvement measures are given, according to the failure reason in each case. Some recommendationsin the design, manufacturing processes and material selections are also discussed here. The results shows that the corrosion control of the aircrafts is a systematic project. In the design, it is necessary to take full account of controlling the factors which affect the corrosion, and pay attention to the details of the anti-corrosion design; In the selection of reasonable anti-corrosion process, the material and process should get a mutual appropriate match, furthermore, the material and its process should adapt to the environment demands.
