摘要
The present invention relates to the composition and methods for obtaining vitreous coatings, obtained by means of a sol-gel process, which are stable at temperatures of up to 250°C, adhere perfectly to various metal surfaces and primers, are uniform, and have amorphous structures that are free of crystallisation and/or precipitates. The invention also relates to a method for protecting a metal surface against corrosion. The procedure involves stabilising Ce3+ ions in the vitreous structure in order to facilitate the distribution or migration thereof to damaged regions when the metal has pits.
