High Temperature Heat Dissipation Coatings

For headers and similar high-heat components, ceramic-based thermal barrier coatings such as chrome oxide, or tungsten carbide matrix coatings, are commonly preferred because they withstand extreme temperature cycling while resisting oxidation. Parkway-Kew's PK-1500 chrome oxide ceramic and tungsten carbide coatings (PK-675, PK-700, PK-750) offer comparable high-temperature durability for demanding component applications.

A heat seal coating is a specialized surface treatment designed to withstand high temperatures while maintaining a tight, wear-resistant seal between moving or mating components. Coatings like nickel chrome boron (PK-920) or tungsten carbide matrices provide this combination of heat resistance and precise sealing performance under extreme operating conditions.

We offer multiple coating technologies including HVOF, plasma spray, metallizing, submerged arc welding, and fuse welding. Each process is matched to specific temperature, wear, and corrosion requirements, with options like tungsten carbide matrix coatings (PK-675, PK-700, PK-750) and nickel chrome boron (PK-920) for demanding thermal environments.

HVOF coatings are applied at speeds exceeding Mach 2, creating an extremely dense, low-porosity coating with strong substrate bonding. This density minimizes heat penetration and oxidation while providing exceptional resistance to wear, erosion, and corrosion in high-temperature industrial applications.

Coating lifespan depends on operating conditions, but our Restore & Grind process allows components to undergo 5-7 cost-effective repairs before requiring full recoating, significantly extending service life. Urethane-coated festoon wheels, for example, last 2-3 years longer than standard OEM parts under continuous heavy use.

Yes. We tailor coating selection, including HVOF, plasma ceramic, submerged arc, and metallizing, based on your equipment's material, operating temperature, load, and wear conditions. This ensures optimal thermal performance and durability whether for wire drawing blocks, fracking plungers, or other heavy industrial components.
