Copper forgings for agricultural machinery are a common mechanical component, and their corrosion resistance and protective measures are the key factors to ensure their long-term use and prolong their life. This paper will introduce the relevant knowledge of agricultural machinery copper forgings from two aspects of corrosion resistance and protection measures.
First of all, let’s take a look at the corrosion resistance of agricultural copper forgings. Due to the particularity of the working environment of agricultural machinery, agricultural machinery copper forgings often come into contact with various corrosive media, such as water, soil, fertilizer and so on. Therefore, agricultural copper forgings need to have good corrosion resistance to resist the erosion caused by these media. In general, the corrosion resistance of agricultural copper forgings can be evaluated from the following aspects:
- Acid and alkali corrosion: In addition to containing a variety of elements, chemical fertilizers commonly used in agricultural machinery operations also contain acid and alkali substances, which may cause corrosion to copper forgings of agricultural machinery. Therefore, the resistance of copper forgings to acid and alkali corrosion can be improved by changing the material composition and adding anti-corrosion elements in production.
- Oxidative corrosion: Agricultural copper forgings are prone to oxidative corrosion in a humid environment. Common protection methods include coating treatment, surface oxidation treatment, etc., in order to increase the oxidation resistance of the surface of agricultural copper forgings.
- Microbial corrosion: Around farmland or agricultural machinery storage, there are often some microorganisms, which will produce acidic substances and attach to the surface of copper forgings of agricultural machinery to cause corrosion. In order to prevent microbial corrosion, regular cleaning, disinfection and other methods can be used to ensure that the surface of agricultural copper forgings is clean and sanitary.
For the corrosion resistance of copper forgings of agricultural machinery, we can also take the following protective measures:
- Surface treatment: The surface treatment of agricultural copper forgings can be done by spraying, coating, heat treatment, etc., to form a protective layer, so as to improve its corrosion resistance and extend its service life.
- Regular maintenance: Copper forgings of agricultural machinery will be affected by various external factors during use, so regular maintenance is very important. Including cleaning, dust removal, lubricating oil and other maintenance measures, can effectively reduce the occurrence of corrosion.
- Material selection: When designing copper forgings for agricultural machinery, materials with good corrosion resistance, such as copper alloy, can be selected. The proper selection of materials can reduce the risk of corrosion.
In summary, the corrosion resistance and protective measures of copper forgings of agricultural machinery are important factors to ensure their normal operation and extend their life. The corrosion damage of copper forgings of agricultural machinery can be effectively reduced and its reliability and service life can be improved by proper corrosion resistant treatment and protective measures.
