氫氧化鉀是我們在初中的時候就了解過的一種堿性物質(zhì)，而且在很多的領(lǐng)域當(dāng)中都是擁有非常好的使用效果，可以在其進(jìn)行使用的時候有人會疑問它和鎂合金的微弧氧化有關(guān)系嗎，，那么我們今天來從這一個方面來講述一下這兩者之間的關(guān)系吧。
Potassium hydroxide is an alkaline substance that we learned about in junior high school, and it has very good use effect in many fields. When it is used, some people will doubt whether it is related to micro arc oxidation of magnesium alloy. So let's talk about the relationship between the two from this aspect.
當(dāng)微弧氧化程度降低的時候會在金屬表面產(chǎn)生微弧光，而之所以會產(chǎn)生微弧光和使用到電壓的電導(dǎo)率是有直接關(guān)系的。當(dāng)電解質(zhì)的導(dǎo)電率更高的時候在轉(zhuǎn)移或者是遷移等離子體的時候效果更好一些，并且在這個過程的當(dāng)中膜層的表面會更加容易的出現(xiàn)一些電弧光，所以在使用的時候降低外部增加的電壓來減少產(chǎn)生的微弧光。
When the oxidation degree of micro arc is reduced, micro arc light will be produced on the metal surface, which is directly related to the conductivity of the applied voltage. When the conductivity of electrolyte is higher, the effect is better when transferring or transferring plasma. In this process, some arc light will appear on the surface of the film more easily. Therefore, reduce the external voltage to reduce the micro arc light.

在硅酸鹽的溶液當(dāng)中添加進(jìn)去適量濃度的氫氧化鉀那么會發(fā)現(xiàn)氧化膜的厚度是又出現(xiàn)變化的。氧化膜層的厚度是隨著濃度的增加而進(jìn)行增加的，不過等到濃度在增加到一定程度的時候厚度增加的頻率是會慢慢降低的，等到在濃度逐漸的增加到一定程度之后厚度是已經(jīng)沒有變化了。所以我們可以看出來濃度再進(jìn)行增加的時候膜層的也是在逐步進(jìn)行增加的。
In the silicate solution to add the appropriate concentration of potassium hydroxide, you will find that the thickness of the oxide film is changed again. The thickness of oxidation film increases with the increase of concentration, but when the concentration increases to a certain extent, the frequency of thickness increase will gradually decrease, and when the concentration gradually increases to a certain extent, the thickness has not changed. So we can see that when the concentration is increased, the film is also gradually increasing.
初次之外我們還會發(fā)現(xiàn)在硅酸鹽溶液當(dāng)中可以堿性物質(zhì)濃度較低的時候依然是可以正常進(jìn)行氧化成膜的。所以其實堿性物質(zhì)在添加進(jìn)去的時候是可以影響膜生成的效率的。
For the first time, we will also find that when the concentration of basic substances in silicate solution is low, it can still be oxidized to film normally. Therefore, in fact, alkaline substances can affect the efficiency of membrane formation.
上面介紹的就是氫氧化鉀和鎂合金氧化之間的關(guān)系，其實我們在更加深入的了解過這個內(nèi)容之后可以更好的對堿性物質(zhì)進(jìn)行應(yīng)用，并且在使用各種材料的時候也是需要選擇更加合適的方式。
The above is the relationship between potassium hydroxide and magnesium alloy oxidation. In fact, we can better apply alkaline materials after a more in-depth understanding of this content, and we also need to choose a more appropriate way when using various materials.
