Example Embodiment

[0024] Example 1: A powder-cored wire for preparing corrosion-resistant Al-Zn-Mg-Ni amorphous nanocrystalline composite coating and its preparation method

[0025] Choose 10×0.4 (width 10mm, thickness 0.4mm) pure aluminum strip, first roll it into a U shape, according to the mass percentage of each element of the powder core: 16% Zn, 18% Mg, 4% Ni, weigh The ingredients are mixed in the powder mixer for 30 minutes, and then added to the U-shaped aluminum belt groove with a filling rate of 38%. Then the U-shaped aluminum belt groove is closed to coat the powder in it, and the powder is drawn through multiple drawing processes. The diameter is reduced to 2.0mm, and finally it is wound into a disc shape required for delivery. After measurement and packaging, a product ready for delivery is formed.

Abstract

The invention discloses a cored wire for preparing an anti-corrosion Al-Zn-Mg-Ni amorphous-nanocrystalline composite coating layer. The cored wire is characterized in that the skin of the cored wire is a pure aluminum belt; a powder core is metal powder of Zn, Mg and Ni, and accounts for 38 to 44 percent of the mass of the wired; and the powder core is prepared from the following components in percentage by mass: 16 to 22 percent of Zn, 14 to 18 percent of Mg and 4 to 8 percent of Ni. The cored wire can be used for preparing an aluminum-based amorphous-nanocrystalline composite coating layer after being machined via a high-speed electric arc spraying technique; the coating layer consists of multiple phases of structures such as an amorphous phase, a nanocrystalline phase and a crystallization phase, and is excellent in corrosion resistance performance; and therefore, the corrosion resistance performance of the surface of a steel structural member can be effectively improved, and the service life can be prolonged.

Description

technical field [0001] The invention belongs to the field of thermal spray coating in the professional surface treatment technology of material processing engineering, and in particular relates to a powder core wire material for preparing corrosion-resistant Al-Zn-Mg-Ni amorphous nanocrystalline composite coating. Background technique [0002] After the chemical or electrochemical reaction between the material and the environment, the corrosion failure of the material will be caused, resulting in the loss of equipment function, causing huge economic losses to the society, and even immeasurable major disasters. Steel is one of the most commonly used equipment materials for human beings, but it is extremely prone to corrosion failure in corrosive media. Therefore, research on how to improve steel anti-corrosion technology has become one of the key concerns of many material researchers. The internal atomic structure of amorphous materials is arranged irregularly and randomly, a...
