Turbine Blade High-Temperature Anti-Wear Coating

Turbine blade high-temperature anti-wear coating, a composite material that combines high-performance wear-resistant ceramic particles with modified toughening heat-resistant resins, demonstrating excellent wear and corrosion resistance.

Product Application

High-temperature resistant ceramic wear-resistant coatings excel in various applications. They are widely used for the repair of turbine blades and pipeline equipment subjected to severe wear and corrosion, as well as for preparing protective coatings on surfaces requiring wear and corrosion resistance. These applications include not only turbine blades but also desulfurization cycle pipelines in power plants, tailings pipelines, coal slurry pipelines, chute equipment, filters, slag flushing pipelines, and water slag separators, among others.

Usage Instructions

Surface Treatment: Prior to starting the repair, the surface of the equipment to be repaired must be roughened. This involves cleaning off oil and moisture, followed by sanding the surface with an angle grinder or sandblasting method to achieve a uniform roughness, enhancing the bonding strength between the repair material and the base material.

Mixing: Combine Components A and B in the specified weight or volume ratio, mix thoroughly, and process with an aging machine. Note that the coated material should be used up within 30 minutes after mixing to prevent premature solidification of the colloid. It is recommended to mix and apply simultaneously, and the mixing quantity should not exceed 1.5 kg at a time.

Coating: The suitable coating thickness for high-temperature ceramic wear-resistant coating is 10-20um. During the coating process, the mixed material should be applied layer by layer to the area to be repaired, ensuring the coating is even. For higher surface requirements, KDNT corrosion-resistant patching surface coating can be used for further repair and surface treatment.

Curing Process: After curing for 24 hours at 25°C, the high-temperature ceramic wear-resistant coating is ready for use. If the ambient temperature is below 10°C, heating measures should be taken or the curing time extended appropriately to ensure the coating fully cures. The cured coating boasts mechanical properties comparable to many metals, performing exceptionally well.

Due to the moderate performance of this high-temperature ceramic wear-resistant coating, increasing the coating thickness in special operating conditions can be relatively easy by using a scraping operation. After scraping, the surface achieves an extremely smooth finish, showcasing excellent corrosion resistance.
