摘要/Abstract

摘要： 为进一步探究微弧氧化膜和7050铝合金的氢脆敏感性之间的关系,采用了湿空气中的慢应变速率拉伸、拉伸断口形貌分析、微弧氧化试样表面形貌分析及氢含量测试等表征手段,验证了微弧氧化膜抑制7050铝合金在湿空气中发生氢脆的机制。结果表明,不同微弧氧化电压下制备的膜层对7050铝合金具有不同的抑制氢脆效果,抑制机制主要由膜阻氢进入试样和膜致附加压应力两个方面组成。

关键词: 7050铝合金, 微弧氧化膜层, 氢脆敏感性

Abstract: In order to further explore the relationship between micro arc oxidation film and hydrogen embrittlement sensitivity, the slow strain rate tensile testing in humid air, tensile fracture morphology analysis, micro arc oxidation surface morphology analysis, hydrogen concentration test and other characterization methods were used to verify the mechanisms of micro-arc oxidation film inhibiting hydrogen embrittlement of 7050 aluminum alloy in humid air. The results show that the micro arc oxidation films under different voltages have different effects on inhibiting hydrogen embrittlement of the alloy. The mechanisms of the inhibition of hydrogen embrittlement by the film are mainly attributed to the repression of hydrogen permeation and the additional film-induced compressive stress.

Key words: 7050 aluminum alloy, micro arc oxidation film, hydrogen embrittlement sensitivity
