Air blower

Abstract

The invention discloses an air blower and a preparation technique thereof, and belongs to the technical field of metal materials. The air blower comprises 0.5-1.5% of Li, 0.1-0.3% of Pt, 0.1-0.3% of Ir, 2-4% of Ni, 0.5-1.5% of Mg, 1-5% of Cu, and the balance Al and impurities. The chemical activity of Li of the raw materials is high and can react with gas elements such as hydrogen, oxygen, sulfurand nitrogen in alloy to generate a chemical compound with a low density and a low melting point, and bubbles and other defects of metal are eliminated. Pt and Ir are likely to form a Pt-Ir binary alloy phase, the expansion coefficient is small, and thus the capacity to resist thermal expansion and cold contraction of aluminum alloy can be improved. Meanwhile, grains are refined through solid solution treatment and aging treatment, so that the alloy has a good mechanical property. A uniform and compact ceramic-like film is formed on the surface of a product through micro-arc oxidation, and thus the product has extremely high resistance in complex and changeable environments.

Description

technical field [0001] The invention relates to a blower and a preparation process thereof, belonging to the field of metal materials. Background technique [0002] From ancient times to the present, the metallurgical industry has always been valued, and the corresponding auxiliary equipment is also changing with each passing day. From the earliest mouth blowing type air blowing to the blower air blowing later, our requirements for air blowing equipment are getting higher and higher, so the blower's The material composition shows its importance. Blowers are usually made of alloy steel or aluminum alloy. [0003] Aluminum alloy refers to an alloy system based on aluminum, adding a certain amount of magnesium, silicon, molybdenum, chromium, manganese and other elements and controlling the content of impurity elements. Aluminum alloy has high strength, high hardness, light weight and good ductility, especially suitable for structural materials, so it is widely used in defense...

AI Technical Summary

Problems solved by technology

General alloy materials and processing methods can be used in common environments, but in-depth research is still needed to improve the performance of aluminum alloys (such as strength and hardness)

[0005] In view of the shortcomings of traditional aluminum alloys such as many cracks and poor elongation, Publication No. 106048379A discloses a method to improve the toughness and elongation of the product by adding rare earth, strontium and other elements into the aluminum alloy.

However, only improving the toughness, elongation and other properties of aluminum alloys cannot make aluminum alloys cope with complex environments.
