储存和使用过程中不会腐蚀储油容器和汽车机件。

As power battery for electric vehicle,lead acid battery has many shortcomings such as low specific capacity,the poor ability of charge acceptance and low active material utilization efficiency;corrosion of grid,sulfating of negative electrode ,hydrogen and oxygen evolution reaction and other phenomena occur during over charge-discharge and cause the capacity loss or fade to the batteries.

作为电动车用电池，铅酸蓄电池仍然存在着比能量低、充电接受能力差、活性物质利用率低等缺点，板栅的腐蚀、负极硫酸盐化、析氢、析氧等现象会引起充放电过程中不必要的副反应，这将导致电池容量的损失及衰减。

In the coating, the nodular defect was observed to worsen severely the properties. For testing under oxidation condition, the nodular defect results in the internal oxidation of Al. No single Al oxide scale may be formed at 1100℃ owing to consumption of Al. Under hot corrosion, it becomes as short-path for diffusion of S through the coating, thus sulphuring the coating together with the substrate. During thermal shock testing, it may act as the source of cracking, and moreover, if cyclic stress applied, the cracks propagate toward the substrate, the thermal fatigue properties of coating will be worsened.

结果表明：在氧化条件下，缺陷导致Al的内氧化，在1100℃时，由于Al的大量内消耗，涂层表面已不能形成单一的氧化铝膜，使氧化性能下降；在热腐蚀条件下，缺陷成为硫向涂层中扩散的通道，导致涂层及基体的硫化；在冷热疲劳条件下，缺陷成为裂纹源，在交变应力作用下，裂纹向基体中扩展，降低了涂层的热疲劳性能。

They are used to solve many problems,for instance,negative pressure fluctuates badly inside the kiln,waste acid water flows off from the rear of the kiln,temperature is kept difficultly,blanking bin at the rear of kiln is corroded seriously,and the service life of the kiln is short.

针对蒸硒回转窑负压波动较大、窑尾冒酸水、温度控制不稳定、窑尾下料箱腐蚀严重、使用寿命短等问题，对蒸硒回转窑采取一系列改造和维护保养措施，取得较好的效果。

这些气 穴通常由具有格外高能量的水蒸气所填充，与混凝土表面的反复接触导致形成凹陷和孔洞，即气蚀。既然高质混凝土也不能抵抗这种劣化，因此最好的补救是通过制造平滑水流来消除气蚀。在所有必须的地方，关键的面上衬以高抗气蚀性的材料。通常，混凝土抗腐蚀和磨损的能力随强度增加而提高。采用硬韧的集料可改善混凝土的抗磨损性。

实用新型的结构是炭刷架(1)用(3)连接不锈的刷子bristl的金属连接器(4)被铸造实用新型有腐蚀抵抗、铁锈抵抗， unhairing抵抗，没有疏松，长的产品使用期限，干净，美好的出现、经济和可实行性的好处。

Carbon tube with high strength, high toughness, corrosion resistance, non-deformation, anti-leakage, anti-aging advantages.

碳素螺纹管具有高强度、高韧性、耐腐蚀、不变形、防渗漏、抗老化等优点。

Here the high chromium content allows the steel to be highly polished and prevents deterioration of the cavity from heat and corrosion.

在这里高的铬含量使钢可以被抛光很多，而不会因为高温和腐蚀而磨损模腔。
