A chromium-free process for providing a metal surface with the properties of corrosion resistance, hydrophilicity, low odor and bioresistance. The process includes initially treating the metal with a solution of fluoride, ziconium and a protic acid. Then, the metal is treated with a solution of water-soluble silicate at an alkaline pH. Rinses are optionally used after each stage, and an oven drying stage is preferred as the final step in the process.

Procédé sans chrome pour obtenir une surface métallique résistant à la corrosion, hydrophile, à une faible odeur et biorésistant. Le procédé comprend le traitement initial du métal avec une solution de fluorure, de zircone et d'acide protique. Ensuite, le métal est traité avec une solution de silicate hydrosoluble et à pH alcalin. Les rinçages après chaque étape sont optionnels, et on préfère un séchage au four comme dernière étape du procédé.
