Cast iron casting coating is a surface coating used to protect cast iron products. It can provide additional functions such as corrosion resistance, oxidation resistance, and wear resistance, extending the service life of cast iron products. In the casting process, the selection and use of coatings are crucial as they can protect cast iron products from erosion and damage from the external environment.

Advantages and characteristics

1. Cast iron casting coatings have good anti-corrosion properties. Due to the frequent exposure of cast iron products to humid, humid, and corrosive environments, they are susceptible to corrosion and oxidation. By using appropriate coatings for treatment, a strong protective film can be formed, effectively isolating the contact between cast iron products and the external environment, thereby reducing the occurrence of corrosion. In addition, cast iron casting coatings can also resist the erosion of harmful substances such as acids and alkalis, providing long-lasting protective effects.

2. Cast iron casting coatings also have excellent antioxidant properties. In high-temperature environments, cast iron products are prone to oxidation reactions, leading to the formation of surface oxide layers and a decrease in the quality of metal materials. Suitable coatings can form a dense oxide barrier layer on the surface of cast iron products, effectively avoiding the problem of iron products being corroded by oxidants. This not only extends the service life of cast iron products, but also improves their performance and quality.

3. Cast iron casting coatings can also provide good wear resistance. During use, cast iron products are often subjected to friction and wear, which can easily lead to surface wear, scratches, and corrosion. By using appropriate coatings for treatment, a hard and wear-resistant coating can be formed, effectively preventing wear and corrosion of cast iron products. This can extend the service life of cast iron products, improve their durability and reliability.
