| 摘 要： | 初步测定了Ｌ２钝铝和ＬＣ４铝合金微弧氧化陶瓷膜生长过程的电流效率。铝微弧氧化电流效率在１０％￣３０％之间变化。相同实验条件下，ＬＣ４铝合金电流效率比纯铝高。陶瓷膜达到一定厚度后，电流效率随氧化时间延长而不断降低。要生长出１μｍ厚的膜，纯铝和ＬＣ４铝合金的耗电量分别约为０．１３ｋＷｈ／ｄｍ＾２和０．１ｋＷｈ／ｄｍ＾２。

| Abstract: | Current efficiency of microarc oxidation on L2 pure aluminum and LC4 aluminum alloy is preliminarily determined. Current efficiency can change between 10% and 30%, but the value for LC4 aluminum alloy is higher than that for pure aluminum under the same experimental conditions. After thickness of the ceramic coating increases to a certain value, current efficiency gradually decreases with oxidation time. The consumption of electric energy for pure aluminum and LC4 aluminum alloy is respectively 0.13 kWh/dm 2 and 0.1 kWh/dm 2 per micron. |
