镀层

Furthermore, the gate is directly sitting on the undoped layer, and it shows larger gate turn-on voltage and broad gate swing.

此外，闸极直接镀於未掺杂层，因此有大的闸极导通电压宽广的闸极电压操作范围。

For corrosion,we should work hard to avoid or slow, therefore introduce emphasisly protection principle and methord of zink coating.

对于腐蚀破坏，我们应力求避免或减缓，因此着重介绍了镀锌层的保护原理及工艺方法。

The paper introduce fundamental theory and viewpoint on corrosion of iron and steel and zink coating, expounding loss and hazerd of corrosion, first.

本文首先介绍了钢铁腐蚀及镀锌层的基本理论与观点，阐述了腐蚀的损失及危害。

Firstly, wherever possible avoid cheap wire, as it often has tags and flakes of zinc on it, and contains high levels of lead. Use some of the newer wires by BHP that are welded after galvanisation.

现在有些新产品在金属电镀后再镀上一层 BHP，当然价钱会比较昂贵，但相对比较花费在治疗和药物的金钱就已经值得！

Adopting cathode protection of the zinc materials as an effective protection method, which already applied more and more in many field. For example, Hot-dip galvanisation, galvanization, electric arc spray zinc 、sherardizing, etc. But that method are with lots of shortcomings. For example, hard to apply

采用锌材料阴极防护的方式，作为一种有效的钢铁防护手段，已经得到越来越多的应用，诸如热浸镀锌、电镀锌、电弧喷锌、热喷锌等工艺手段，但鉴于这些工艺存在施工难度大、环境污染重、能耗高、锌层受损难修复等弊端，使得发展受限。

The amorphous phase is found in the outer layer of hot-dip aluminized layer.

结果发现，镀铝层的表面层存在非晶态金属相。
