Which chemical conversion material is specifically used for treating magnesium surfaces?

The chemical conversion material specifically used for treating magnesium surfaces is AMS-M-3171 Type VI. This material is designed to provide corrosion resistance and enhance paint adhesion on magnesium alloys, which are particularly susceptible to corrosion due to their reactive nature with environmental elements. The treatment helps to form a protective layer that reduces the likelihood of oxidation and degradation of the magnesium surface.

In contrast, other options such as surface treatment chemical MIL-C-85163 and common corrosion inhibitor MIL-PRF-87937 either pertain to different materials or are more general treatments not specifically tailored to magnesium. Acid cleaning solution MIL-PRF-174A is focused on cleaning surfaces rather than providing the corrosion protection or conversion that magnesium requires. Therefore, AMS-M-3171 Type VI is the correct material for effectively treating magnesium surfaces to prevent corrosion and maintain the integrity of the material.
