我还没有听说二氧化硫腐蚀的不锈钢并且我不认为它能腐蚀。

The paper solved the problems of less valid data in thermal infrared imager,impurity being on surface of specimen and uneasy dipartite corrosion area in image which happened in detection of structure parts' hidden corrosion by thermal wave imaging.Firstly,the contrast of one unheated image was enhanced by self-adaptive mathematical morphology sharpening,and then location of the impurity was confirmed by change of the image grads.

针对飞机结构隐藏腐蚀热波成像检测中出现的试件表面存在杂物、热像仪中有用数据较少、图像序列中腐蚀区域不明显等情况，首先通过对加热前的一幅图像进行自适应形态学锐化处理，提高图像的对比度，并根据图像梯度的变换情况确定出杂物的位置。

Results show that the alumina formed on the corroded NiCoCrAlY coating is roughness, cracked and incontinuous and many pits was formed on the surface of the coating after the salt-spray test.

试验结果表明：经过盐雾腐蚀的涂层表面的均匀性和完整性均被破坏，涂层表面产生了大量的腐蚀坑；高温循环氧化以后，表面形成的Al2 O3 氧化膜变得粗糙、破碎且不连续，而且氧化膜容易剥落，降低了涂层的高温抗氧化能力，缩短了涂层的使用寿命

There is no nonuniform corrosion (such as spot corrosion, intercrystalline corrosion etc.) on stainless steel in mud acid solution with the corrosion inhibitor.

在该缓蚀剂存在的土酸介质中，不锈钢不产生点蚀、晶间腐蚀等非均匀腐蚀现象。

The results show that Sb addition can diminish the crystal grain, but the content of segregative phase at crystal boundary increases, and the current efficiency of material is low. Compared with Sb addition, Sn addition can also diminish the crystal grain, the current efficiency increases, the content of segregative phase at crystal boundary reduces, but diffusional corrosion of the anode surface is not uniform. The cooperation of Sb and Sn can prevent Si from segregating effectively and enhance the current efficiency obviously. At the same time, anode materials have preferable surface dissolution characteristics.

结果表明： Sb具有细化晶粒的作用，但晶界存在较多偏析相，电流效率偏低；与Sb相比较， Sn也具有细化晶粒的作用，电流效率有所提高，晶界偏析相较少，但阳极的表面腐蚀溶解不均匀； Sn和Sb的协同作用在于能有效地抑制Si的偏析，显著提高阳极的电流效率，使得阳极表面具有良好的腐蚀溶解性。

It has been found that flip chip without and with underfill encapsulation has different corrosion modes. Possible failure mechanism was presented.
