Abstract

The invention discloses a novel hot dip coating low-cost low-energy-consumption aluminum tin alloy containing Ti and Y. The alloy comprises the ingredients of, in percentage by weight, 0.3-0.5% of Na,1.5-1.8% of Ti, 0.4-0.8% of Ca, 15.0-22.0 % of Sn, 0.2-0.4% of Y, 0.3-0.5% of Yb, 0.1-0.2% of P and the balance aluminum. By means of the hot dip coating aluminum tin alloy, the key problems that thetechnology in the present hot dip coating alloy field lags behind, product quality is poor, the product cost is high, energy consumption is large, and the like are solved, and in the near future, thealloy will be applied to more fields more widely.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an aluminum-tin alloy. Background technique [0002] Reinforced concrete refers to a composite material formed by adding steel mesh, steel plates or fibers to concrete. Corrosion of steel bars and freeze-thaw cycles of concrete can damage the structure of concrete. When rebar corrodes, the rust spreads, cracking the concrete and losing the bond between the rebar and concrete. When water penetrates the concrete surface and enters the interior, the frozen and condensed moisture expands in volume, and after repeated freeze-thaw cycles, cracks are formed in the concrete microscopically and continue to deepen, thereby crushing the concrete and causing permanent and irreversible damage to the concrete damage. Corrosion of steel bars in highway bridges is relatively common, which seriously threatens the safety and durability of highway bridge structures. [0003] Corrosion of steel b...
