Dissolving sample with nitric acid and hydrofluoric acid, the silicon content of silicon-manganese alloy was made a measurement with ICP-AES method in the hydrofluoric acid-resistant spray devices.

用硝酸和氢氟酸溶解试样，采用耐氢氟酸雾化装置，用ICP - AES法测定硅锰合金中的硅。

The results show that a compact oxidation film on surface of magnesium alloy can be deposited under micro-arc restrained, which is harder and more resistant to acid and alkali.

结果表明，在抑制阳极发生弧光放电的状态下，镁合金表面可以沉积一层致密的氧化厚膜层，该膜层具有较高的硬度和优良的耐蚀性能。
