Problems solved by technology

Due to the chemical composition of the 316L alloy steel matrix, the weight percentage of each component, and its metallographic structure, etc., compared with low carbon steel, there are obvious differences and significant characteristics. Therefore, in 316L alloy steel The enamel process is implemented on the surface to obtain an enamel coating with superior performance, which ensures good adhesion (the bonding force between the enamel layer and the substrate), and there is still no public report

Abstract

The invention discloses a film structure of a 316L alloy steel surface enamel coating. The film structure of the 316L alloy steel surface enamel coating is mainly characterized in that a 316L alloy steel substrate (1), a reconstruction shallow surface layer (2), an intermediate layer (3) and a surface layer (4) forms a four-layer complex enamel film, and components of an enamel material for the intermediate layer (3) and the surface layer (4) and weight percentage of each component are also disclosed. The film structure of the 316L alloy steel surface enamel coating has the characteristics of reasoned and advanced structure, good corrosion resistance, strong friction pull and the like, and the obtained 316L alloy steel surface enamel coating part can be widely applied to various fields.

Description

technical field [0001] The invention relates to a film layer structure of an enamel layer on the surface of 316L alloy steel, which belongs to the surface treatment technology of metal materials. Background technique [0002] Enamel (also known as glass-lined) technology on the surface of metal materials has significant positive significance for effectively improving the corrosion resistance and chemical reaction resistance of the surface of metal materials, expanding its application range and improving its service life. [0003] The 316L alloy steel involved in the present invention is OOCr17Ni14M02 alloy steel. Its characteristics are mainly reflected in the "three excellent" aspects of corrosion resistance, especially pitting resistance, high temperature strength and work hardening, so it has a wide range of applications in industry, marine and aerospace. [0004] However, 316L alloy steel (alloy stainless steel) works in harsh environments containing corrosive media suc...
