Problems solved by technology

[0005] However, in the prior art, due to the fact that the arc spraying technology itself is susceptible to oxidation and other factors in the air, the prepared iron-based amorphous coating has a low amorphous content and a large porosity, which makes the coating quality not high. , and most of the powder core wire materials are added with noble metal elements, rare earth elements or simple powders with relatively high purity requirements, which greatly increases the cost of the powder core wire materials and reduces the practical use of arc sprayed iron-based amorphous coatings in industry Rate

Abstract

The invention provides a powder core wire material which comprises a powder core, wherein the powder core is prepared from the ingredients of 15 to 25wt% of Cr, 5 to 15wt% of Mo, 5 to 15wt% of Al, 1 to 5wt% of B, 1 to 5wt% of Si and the balance of Fe. According to the powder core wire material disclosed by the invention, ingredients of the powder core are specifically controlled; under the comprehensive action of all ingredients in the powder core and the ingredient content, an amorphous coating layer obtained by electric arc spraying the powder core wire material has the advantages of high amorphous content, good hardness and good anticorrosive performance; furthermore, the raw materials of the powder core wire material is low in cost, and the powder core wire material does not contain precious metal elements, is low in preparation cost and can be widely applied to the technological fields of corrosion resistance, wear resistance and the like in a large scale. The invention also provides a preparation method of the powder core wire material.

Description

technical field [0001] The invention relates to the technical field of wire materials, in particular to a powder core wire material and a preparation method thereof. Background technique [0002] Amorphous materials have excellent hardness, strength, corrosion resistance and wear resistance compared with crystal alloy coatings of the same composition because they do not have the defects of crystal materials such as grain boundaries, precipitated phases and composition segregation. However, the preparation of amorphous bulk materials requires a rapid solidification process, which requires harsh process conditions, making the preparation technology very difficult, and the disadvantages of brittle fracture at room temperature limit its industrial application. Amorphous materials with unique properties applied in the form of coatings not only overcome the shortcomings of bulk amorphous materials, but also extend the excellent performance of amorphous materials, making it possibl...
