Colour low-melting one-layer vitreous enamels for steel wares
The compositions of one-layer vitreous enamels is developed which permit to obtain a broad scale of colours of coatings for steel wares with sufficiently well quality of surface. A variety of different dyes was tested. For the most optimal coatings, some properties were studied such as chemical stability, adhesion strength, brightness and thermal stability. Temperature interval of burning covers is also determined as average 670...740°С. The colorimetry parameters of one-layer itreous enamels were determined or calculated. The obtained enamel coatings can be applied in mass production.
