Two types of thermally durable and heat-resistant enamel coatings were applied to steel alloys. Three-layer TiO2-SiO2 sol-gel films were grown by a dip-coating method on an enamelled metal alloy to maintain and protect their properties from undesired environmental impact. The enamel coatings withstood 6000 h at 600 °C, retaining their colour while staying hard and adhering firmly to the metal surface. A three-layer sol-gel coating improved the chemical resistance of the enamelled metal by 6% (0 h), 29% (3000 h), and 28% (6000 h) at 600 °C. Throughout the whole treatment at 600 °C, the enamel coatings maintained their microhardness and even increased it from 3.6 to 4.4 GPa.
