FeNiCrAl-based multi-principal element alloy transparent glaze glaze and its glazing process

technical field

The invention belongs to the technical field of glazes, and in particular relates to a FeNiCrAl-based multi-principal alloy transparent glaze and a glazing process thereof.

Background technique

Glaze is a thin, colorless or colored glassy layer covering the surface of an object. The glaze layer can increase the mechanical strength of the product, beautify the utensils, and make the utensils have the characteristics of acid and alkali resistance and wear resistance. At present, the glazes acting on metal surfaces are mainly enamel glazes, which are glazes that can be firmly combined with metal bodies after being fired on steel, cast iron, aluminum, copper and stainless steel. layer. Since the metal and the glaze layer are two different substances with large differences in thermal expansion coefficients, one method of enamel preparation is to first apply an opaque bottom glaze on the metal substrate as a transition layer to reduce the gap between the metal and the surface glaze. The stress, and then coat the top glaze to give the product a smooth and beautiful surface. Or use a one-shot enamelling process, where the glaze acts as both a base glaze and a top glaze, applied and fired in one pass. Due to the presence of the underglaze, these methods lack the transparency of the enamel. In addition, the firing takes a long time, usually 3 to 5 hours, which greatly restricts the production efficiency.

Compared with traditional alloys, the different phase composition and microstructure of FeNiCrAl-based multi-principal alloys limit its glaze layer preparation. The main reason is that the alloy is composed of FCC (L1 ₂ ) and B2 (BCC) phases, the FCC phase is mainly rich in Fe and Cr elements, and the B2 phase is mainly rich in Ni and Al elements. The difference in the composition of the two phases and the difference in the expansion coefficient can easily cause the glaze layer to fall off, and the existing glaze materials and processes cannot meet the production needs. Therefore, it is very necessary to study the glaze composition and glazing process of the glaze layer of FeNiCrAl-based multi-principal component alloy.
