Abstract

The invention provides a method for preparing a nickel-base amorphous coating on a carbon steel surface, and belongs to the technical field of materials. The method comprises the following steps: (1) placing a carbon steel matrix in water for electrodialysis to obtain a conducting carbon steel matrix; (2) soaking the conducting carbon steel matrix in de-stressing solution, washing and drying; (3) placing the dried matrix in degreasing solution, adding sodium pyrophosphate, performing heat preservation and then washing; (4) soaking the matrix in neutralizing solution and then washing; (5) placing the matrix in crystallization solution and then washing, and placing in sodium orthophosphate solution and then washing; (6) placing the matrix in adjusting solution and then washing; (7) placing the matrix in activation solution and then washing; and (8) treating the matrix in amorphous treating fluid and then washing to finally obtain the carbon steel matrix with the nickel-base amorphous coating. The method is simple and convenient in operation; and the obtained nickel-base amorphous coating has the advantages of high hardness, excellent corrosion resistance, excellent wear resistance and beautiful appearance, and can be applied to decorative materials.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a method for preparing a nickel-based amorphous coating on the surface of carbon steel. Background technique [0002] As a special form of metal, amorphous material has high corrosion resistance, high wear resistance, high hardness and superior decorative performance, and has a wide range of applications in transportation, communication, aviation, aerospace and other fields. However, the preparation process of existing amorphous materials is complex, which limits its application in some fields. Due to the high brittleness of amorphous materials and the rapid formation of an inert oxide layer on the surface in the atmospheric environment, the preparation of amorphous coatings on metal surfaces by conventional methods is limited to a certain extent. At present, the preparation method of amorphous materials is mainly crystal growth, which is complicated in process, expensive in e...
