Introduction
Handles are an essential element of any product that requires opening or closing, such as doors, windows, and cabinets. Zinc alloy handles are popular due to their excellent strength, durability, and aesthetic appeal. However, their resistance to oxidation and corrosion can vary significantly depending on the composition and manufacturing process. This article aims to research and compare the oxidation and corrosion resistance performance of zinc alloy handles.
Research Methodology
Several zinc alloy handle samples were selected for this research. The samples were subjected to various tests to determine their oxidation and corrosion resistance performance. The tests included salt spray testing, humidity testing, and electrochemical testing. The samples were also analyzed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) to investigate their microstructure and elemental composition.
Results and Discussion
1. Salt spray testing results showed that the handles with a higher percentage of aluminum had better corrosion resistance than those with a lower percentage. This is because aluminum forms a protective oxide layer on the surface of the handle, which prevents further corrosion.
2. Humidity testing revealed that the handles with a higher percentage of copper had better oxidation resistance than those with a lower percentage. This is because copper forms a stable oxide layer that protects the handle from further oxidation.
3. Electrochemical testing results showed that the handles with a higher percentage of zinc had better corrosion resistance than those with a lower percentage. This is because zinc sacrificially corrodes to protect the handle from corrosion.
4. SEM and EDS analysis showed that the handles with a more uniform microstructure had better oxidation and corrosion resistance than those with a non-uniform microstructure.
5. The manufacturing process also played a significant role in the oxidation and corrosion resistance performance of the handles. Handles that were properly cleaned and treated before plating had better resistance to oxidation and corrosion than those that were not.
6. The results of this research suggest that the composition and manufacturing process of zinc alloy handles can significantly affect their oxidation and corrosion resistance performance.
7. Manufacturers should consider the results of this research when designing and producing zinc alloy handles to ensure that they have excellent resistance to oxidation and corrosion.
