Electrolyte solution for anodizing valve metals in the production of insulating or dielectric films, surgical implants or low friction coatings

摘要

An electrolyte solution, containing glycerin and an acidic organic salt and/or inorganic salt and having an acidic pH, is new. An Independent claim is also included for anodizing a metal using the above electrolyte solution. Preferred Features: The electrolyte solution is produced by dissolving an acidic salt (especially p-toluene sulfonate) in glycerin or adding acidic and basic ionic components (especially potassium acetate and sulfuric or tartaric acid) to glycerin, followed by heating to above 150 deg C.
