Potassium hydroxide is an alkaline substance we knew in junior high school, and it has very good use effects in many fields. When it can be used, some people will question whether it has anything to do with the micro arc oxidation of magnesium alloy. Let's talk about the relationship between the two from this aspect today.

当微弧氧化程度降低的时候会在金属表面产生微弧光，而之所以会产生微弧光和使用到电压的电导率是有直接关系的。当电解质的导电率更高的时候在转移或者是迁移等离子体的时候效果更好一些，并且在这个过程的当中膜层的表面会更加容易的出现一些电弧光，所以在使用的时候降低外部增加的电压来减少产生的微弧光。

When the degree of micro arc oxidation decreases, micro arc light will be generated on the metal surface, and the reason for the generation of micro arc light is directly related to the conductivity of the voltage. When the conductivity of the electrolyte is higher, the effect is better when transferring or migrating the plasma, and some electric arc light will appear more easily on the surface of the film in this process. Therefore, when using, reduce the external increased voltage to reduce the generated micro arc light.

在硅酸盐的溶液当中添加进去适量浓度的氢氧化钾那么会发现氧化膜的厚度是又出现变化的。氧化膜层的厚度是随着浓度的增加而进行增加的，不过等到浓度在增加到一定程度的时候厚度增加的频率是会慢慢降低的，等到在浓度逐渐的增加到一定程度之后厚度是已经没有变化了。所以我们可以看出来浓度再进行增加的时候膜层的也是在逐步进行增加的。

If an appropriate concentration of potassium hydroxide is added to the silicate solution, it will be found that the thickness of the oxide film changes again. The thickness of oxide film increases with the increase of concentration, but the frequency of thickness increase will slowly decrease when the concentration increases to a certain extent, and the thickness has not changed after the concentration gradually increases to a certain extent. Therefore, we can see that when the concentration increases again, the of the film is also gradually increasing.

初次之外我们还会发现在硅酸盐溶液当中可以碱性物质浓度较低的时候依然是可以正常进行氧化成膜的。所以其实碱性物质在添加进去的时候是可以影响膜生成的效率的。

For the first time, we will also find that when the concentration of alkaline substances in silicate solution is low, it can still be oxidized into film normally. Therefore, in fact, when alkaline substances are added, they can affect the efficiency of membrane formation.

上面介绍的就是氢氧化钾和镁合金氧化之间的关系，其实我们在更加深入的了解过这个内容之后可以更好的对碱性物质进行应用，并且在使用各种材料的时候也是需要选择更加合适的方式。

The above describes the relationship between potassium hydroxide and magnesium alloy oxidation. In fact, after a deeper understanding of this content, we can better apply alkaline substances, and we also need to choose a more appropriate way when using various materials.
