【摘要】在实验室模拟条件下(25℃,85%±5%RH),通过失重法、扫描电镜、傅立叶红外光谱和X射线衍射研究了可溶盐和SO2对AZ91D镁合金大气腐蚀行为的影响。结果表明:可溶盐和SO2气体均能明显地加速AZ91D镁合金的腐蚀,而且两者之间对其腐蚀具有协同作用。对其腐蚀机理和协同作用进行了讨论。更多还原

【Abstract】 The atmospheric corrosion behavior of diecast AZ91D magnesium alloy deposited with different salts and in the presence of SO₂（25℃ and 85%±5% RH） was studied by gravimetry,Fourier transform infrared spectroscope,scanning electron microscopy and X-ray diffraction.The result shows that there is synergetic effect of the soluble salts and SO₂.Both the soluble salts and SO₂ can accelerate the atmospheric corrosion of AZ91D magnesium alloy.The synergetic effect of the soluble salts and SO₂ may enable the atmospheric corrosion of metallic materials greater than that caused by single component of the two respectively.更多还原
