AI Technical Summary
Existing coating materials are insufficient to effectively protect flue gas duct equipment under high temperature, abrasion and chemical corrosion environments, especially under high temperature flue gas and dust impact, where the corrosion resistance of coating materials is inadequate.
It adopts a high-temperature anti-oxidation and wear-resistant coating material, which contains chromium, nickel and metal ceramic powder. The ceramic powder is Cr3C2 and CeO2, and the metal powder is Fe, Al and Ti. The coating is formed on the substrate surface through supersonic flame spraying technology. The ratio and particle size of metal powder and ceramic powder in the coating material are precisely controlled, resulting in high bonding strength and resistance to high temperature, wear and acid and alkali.
The coating material exhibits excellent anti-oxidation, anti-wear, and anti-corrosion properties under high-temperature environments, with a service life of over 10 years. It has high bonding strength, is not easy to peel off, and significantly improves the corrosion resistance of flue gas pipeline equipment.
