Description
Technical Field
The invention belongs to the technical field of glazes, and particularly relates to a FeNiCrAl-based multi-element alloy transparent glaze and a glazing process thereof.
Background
The glaze is a thin layer of colorless or colored glass state which covers the surface of the article. The glaze layer can increase the mechanical strength of the product and beautify the ware, so that the ware has the characteristics of acid and alkali resistance and wear resistance. The glaze material acting on the metal surface at present mainly takes enamel glaze as a main material, and the enamel glaze is a glaze layer which is coated on metal blanks such as steel, cast iron, aluminum, copper, stainless steel and the like and can be firmly combined with the metal blanks after being sintered. Because the metal and the glaze layer are two different substances with larger difference of thermal expansion coefficients, one method for preparing the enamel glaze is to firstly coat an emulsion base glaze as a transition layer on a metal substrate, reduce the stress between the metal and the surface glaze, and then coat the surface glaze to endow the product with a smooth and attractive surface. Or using a primary enameling process, wherein the glaze is used as both the ground glaze and the overglaze, and is coated and fired once. These methods lack the clear feel of enamel due to the presence of the primer. In addition, the firing time is long, generally 3-5 hours are needed, and the production efficiency is greatly restricted.
The FeNiCrAl-based multi-element alloy is a novel structural material and has the characteristics of high strength, high hardness, high wear resistance and high corrosion resistance. Compared with the traditional alloy, the different phase compositions and microstructures of the FeNiCrAl-based multi-element alloy limit the preparation of the glaze layer. Mainly because the alloy is composed of FCC (L1 2 ) And a B2 (BCC) phase, the FCC phase being mainly rich in Fe and Cr elements, and the B2 phase being mainly rich in Ni and Al elements. The difference of two phase compositions and different poles of expansion coefficients are easy to cause the falling of the glaze layer, and the existing glaze and technology can not meet the production requirements. Therefore, it is necessary to investigate the glaze composition of the glaze layer of the FeNiCrAl-based multi-element alloy and the glazing process thereof.
