Abstract

The invention discloses a zinc-aluminum-nickel alloy co-penetration agent for bridge embedded parts. The raw materials include the following components in parts by mass: 100 parts of zinc powder, 10-20 parts of aluminum powder, 80-100 parts of aluminum oxide powder, and nickel powder 10 to 30 parts, 2 to 10 parts of rare earth metal oxide powder, 0.1 to 2.0 parts of catalyst, the particle size of the above raw materials is 300 mesh; the zinc powder, aluminum powder, alumina powder, nickel powder and rare earth powder in the above raw materials The metal oxide powder is mixed evenly, heated to 150-200°C, kept for 30-50 minutes, cooled to room temperature, and then mixed with the catalyst to prepare the zinc-aluminum-nickel alloy co-penetrating agent. The zinc-aluminum-nickel alloy co-infiltration anti-corrosion protection layer obtained by applying the invention has the advantages of uniform thickness and compact metallographic structure, excellent corrosion resistance to high-temperature salt spray gas, and no hydrogen embrittlement phenomenon.

Description

technical field [0001] The invention relates to the technical field of multi-element alloy co-infiltration metal anticorrosion, in particular to a zinc-aluminum-nickel alloy co-infiltration agent for bridge embedded parts. Background technique [0002] Every year, the world's steel corrosion loss accounts for more than 10% of the total steel output, and the economic loss caused by corrosion in industrially developed countries accounts for more than 2% to 4% of the total output value of the national economy; research and develop advanced anti-corrosion technology to reduce economic losses caused by corrosion Prolonging the service life of steel and other metal materials and equipment is of great significance to promoting the development of advanced technology, cutting-edge science and defense industry, as well as the sustainable and coordinated development of the national economy and social environment. The embedded parts of bridges with reinforced concrete structure are pron...
