Recent advancements in corrosion protection technologies are set to significantly impact the construction sector, particularly for industries reliant on durable materials. A study published in ‘Cailiao Baohu’, which translates to ‘Materials Protection’, highlights the promising potential of zinc-nickel alloy films created through magnetron sputtering technology. This innovative approach could enhance the longevity and performance of structural components, particularly in aviation and construction applications.
The research, led by Yuan Jingzhui and colleagues from AECC Guizhou Honglin Aviation Power Control Technology Co., Ltd., and the State Key Laboratory of Solid Lubrication at the Lanzhou Institute of Chemical Physics, delves into the effects of zinc and nickel target currents on the properties of these alloy films. The findings reveal that the microstructure and corrosion resistance of the films can be finely tuned by adjusting the nickel content. “The film with a nickel content of 7.63% showed the best corrosion resistance, but it lacked mechanical performance,” explains Yuan. “In contrast, a higher nickel content of 12.88% resulted in excellent corrosion resistance and superior mechanical properties.”
The implications of this research are particularly relevant for the construction industry, where the durability of materials is paramount. With the ability to produce films that not only resist corrosion but also maintain structural integrity, manufacturers can expect to see a reduction in maintenance costs and an increase in the lifespan of components. This could lead to significant savings over time, making projects more economically viable.
Moreover, the study’s focus on the corrosion products, specifically Zn5(OH)8Cl2·H2O, which exhibit passivation effects, presents a further layer of protection against environmental factors. This characteristic is crucial for structures exposed to harsh conditions, as it can prevent the degradation of both the alloy film and the underlying substrate.
As the construction sector continues to seek innovative solutions to enhance material performance, the findings from this research could pave the way for new standards in protective coatings. The ability to customize alloy compositions for specific applications not only enhances performance but also aligns with sustainability goals by extending the life cycle of critical infrastructure.
