Problems solved by technology

The existing reports related to powder core wire materials that can be used for high-speed arc spraying to prepare aluminum-based amorphous nanocrystalline coatings show that there are some shortcomings: first, too many elements are added, which is not convenient for theoretical research and optimization adjustment; Second, the amorphous content is low (less than 30%) and the crystal content is high, which fails to give full play to the unique performance characteristics of amorphous alloy materials; third, the excessive pursuit of the role of rare earth elements in promoting the formation of amorphous leads to the preparation of higher cost

Abstract

The invention discloses a powder core wire for preparing an Al-Ni-Nb-Co amorphous coating through a high-speed electric arc spraying technology. The powder core wire is characterized in that a sheath of the powder core wire is made of a pure aluminum strap, the mass percentage of the powder core wire ranges from 34% to 38%, and components of a powder core comprise, by mass, 12%-16% of Ni, 12%-16% of Nb and 6%-10% of Co. The powder core wire has a high amorphous forming ability, the amorphous content in the coating prepared through the high-speed electric arc spraying technology is high, and the powder core wire has anticorrosion and wear-resisting dual functions, and can provide a firm material guarantee for surface protection of steel and light-alloy parts.

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 is mainly applied to the surface protection of steel structures and light alloy components in service under the interaction conditions of corrosion and wear. Background technique [0002] According to statistics, in 2014, my country’s economic losses caused by corrosion exceeded 2 trillion yuan. Therefore, it is urgent to improve material surface anti-corrosion technology and develop new material support systems. In recent years, amorphous alloy materials have become one of the most concerned materials at the beginning of this century due to their excellent mechanical, anti-corrosion and wear-resistant properties. Amorphous alloys have no structural defects such as grain boundaries, dislocations, and stacking faults, and have uniform structures, high hardness and excellent anti-corrosion properties; some n...
