Fe-based amorphous nano-coating powder and its argon atomization production

Abstract

A Fe-based amorphous nano-crystal spraying powder and its argon atomizing production are disclosed. The spraying powder consists of Cr 8-15wt%, Ni 8-16wt%, Si 2.8-5.7wt%, B 2.8-5wt%, W 2-8wt%, Mo 2-8wt%, Co 0.5-1wt%, Al 1-4wt% and Fe residues. The process is carried out by proportioning for ingredients, vacuum smelting, atomizing and screening powders. It has excellent fluidity and stability.

Description

technical field The present invention relates to the technical field of amorphous and nanocrystalline powders, in particular to a Fe-based amorphous and nanocrystalline spray powder and an argon atomization preparation method thereof. Background technique Amorphous-nanocrystalline materials have more unique and excellent properties than traditional materials, and are promising new materials. However, in practice, until now, these materials have not been widely used. The main factor is that their preparation process is difficult to control, and their applications are mainly limited to low-dimensional shapes such as thin strips, filaments, and powders. Relatively speaking, the preparation process of amorphous and nanocrystalline coatings is relatively easy to realize. Among many methods of preparing coatings, thermal spraying technology is a very competitive technology, and it is also a very promising technology. The use of thermal spraying technology to obtain amorphous-nan...
