Alternative to chrome in place of sealing after anodizing

We require an alternate to chrome which is used for sealing after anodizing at 18-20 degree in 10% sulfuric acid.
Please sggest us a suitable alternative.

The simplest alternative would probably be almost-boiling water. But there are nickel acetate seals, nickel fluoride seals, and others. The chromium is contributing to corrosion resistance and you must test your new seal to make sure you don't suffer and unacceptable drop in corrosion resistance.
