Abstract

The invention discloses zinc-nickel alloy for rebar hot dipping in a road bridge concrete snow clearing agent environment and a processing technology of the zinc-nickel alloy. The zinc-nickel alloy comprises the components of, by weight, 0.2%-0.4% of Ca, 2.0%-2.5% of Ni, 0.2%-0.3% of Pr, 25.0%-28.0% of Al, 0.3%-0.5% of Y, 0.1%-0.2% of Eu, 1.2%-1.5% of Si, and the balance zinc. The development andindustrialization of the zinc-nickel alloy have significance for achieving anticorrosion of road steel members in an increasingly serious environment corrosion state, for lowering road maintenance cost, for quickening metallurgical industry restructuring of our country, and for improving competitiveness.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a zinc-nickel alloy. Background technique [0002] Reinforced concrete is a structural material composed of Portland cement, aggregate gravel, sand and steel bars, and is widely used in roads, bridges and other structures. Under normal conditions, the corrosion of reinforced concrete in the natural environment is not serious, so it has not attracted enough attention. With the deterioration of environmental pollution, the content of corrosive substances in the environmental medium increases, and the phenomenon of concrete structure damage is becoming more and more serious. The corrosion of steel bars in the corrosion of reinforced concrete belongs to electrochemical corrosion. [0003] In road and bridge engineering, the environment of reinforced concrete belongs to the natural environment. Corrosion problems in natural environments are less pronounced than in industrial environ...
