Abstract

The invention discloses an aluminum-based amorphous nano composite powder core wire material and a preparation method of the aluminum-based amorphous nano composite powder core wire material. The wirematerial is made of a powder core wrapped with pure aluminum belt outer skin, and by mass percentage, the powder core accounts for 40-48% of the powder core wire material. The powder core is formed by mixing following alloy powder, and the powder core comprises, by mass percentage, 4-8% of chromium, 2-7% of silver, 2-6% of nickel, 1.5-6% of nano silicon carbide, 3-12% of nano alumina, 1-7% of nano magnesium oxide and the balance iron. Compared with the prior art, the aluminum-based amorphous nano composite powder core wire material and the preparation method have the following beneficial effects that the aluminum-based amorphous nano composite powder core wire material easily forms an oxide passivation film on the surface in a corrosive medium, and the corrosion resistance of the coatingis improved effectively while the overall hardness of the coating is not lowered; and the preparation process of the aluminum-based amorphous nano composite powder core wire material is simple, the time is short, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of material processing engineering and relates to a powder core wire material, in particular to an aluminum-based amorphous nanocomposite powder core wire material and a preparation method thereof. Background technique [0002] The content of aluminum in the earth's crust ranks first among the metal elements. It is very rich in resources, excellent in performance, and has a wide range of applications. Since a thin and dense oxide film is easily formed on the surface of aluminum, it can effectively prevent the diffusion of corrosive media into the metal, so it is endowed with excellent corrosion resistance, and it can also be used in environments with a certain degree of corrosion instead of steel. . However, compared with steel, aluminum alloy, as a soft material, often exhibits the disadvantages of low hardness and poor wear resistance, and is not suitable for service in working conditions with wear.
