Abstract	Sol–gel pretreatments and coatings are an important class of passive coatings primarily used to increase adhesion of subsequent layers to metallic substrates herby improving the protection against corrosion. Sol–gel chemistry has been broadly used as an appropriate method for versatile implementation of extrinsic self-healing in coatings. Nevertheless, it is only recently that such a chemical approach to the development of intrinsic healing coatings has been proposed. Authors review the literature pertaining to the introduction of extrinsic and intrinsic self-healing routes into sol–gel coatings. The development of active sol–gel coatings capable of recovering their protective functionality is based on the broad chemical diversity of precursors and the low processing temperatures required for this type of chemistry.
