Abstract:
A stable trivalent chromium coating solution can be prepared by heating the chromium coating solution and adjusting the pH of the chromium coating solution. The coating solution can be heated to at least 35° C. for no more than 24 hours. While the solution is hot, a basic or acidic material can be added to increase or reduce the pH to a target value, respectively. In some embodiments, the chromium coating solution can have a pH of 3.5 to 4.0 and the pH can vary no more than ±0.15 while in storage for at least 20 days. The trivalent chromium coating solution can include a fluoride compound, a zirconate compound, a corrosion inhibitor compound, a chelating agent, a phosphorous compound, and/or other compounds.

Claim (Index 18):
The trivalent chromium coating solution of  claim 16  comprising trivalent chromium sulfate.
