Corrosion Protection Coatings

For galvanic corrosion prevention, thermally sprayed coatings such as HVOF-applied tungsten carbide or nickel chrome alloys are excellent choices. These coatings create an electrochemically stable surface barrier that isolates dissimilar metals, reducing galvanic reaction. Parkway-Kew's PK-730 tungsten carbide and PK-62 nickel chrome coatings are specifically engineered for heavy-duty corrosive service conditions.

Parkway-Kew offers five primary coating technologies: HVOF (High Velocity Oxygen Fuel) spray, plasma ceramic spray, metallizing, submerged arc welding, and fuse welding. Each technology is selected based on the application's wear, corrosion, and surface finish requirements, ensuring optimal performance and longevity for components like wire drawing blocks, fracking plungers, and industrial pulleys.

HVOF sprays coating material at speeds exceeding Mach 2, producing an extremely dense, low-porosity layer that is far more resistant to corrosion than conventional spray methods. The resulting coating has minimal oxidation and superior adhesion, effectively shielding components such as fracking plungers and wire drawing blocks from corrosive chemicals, moisture, and wear.

Yes. Parkway-Kew's Restore & Grind process fills and blends worn or corroded areas on components like wire drawing blocks, allowing 5 to 7 cost-effective repairs before a full recoat is required. This significantly extends service life, reduces replacement costs, and minimizes production downtime without compromising surface quality or coating integrity.

Oil and gas (fracking), wire drawing and wire mills, shipping terminals, and heavy industrial manufacturing benefit most from Parkway-Kew's corrosion protection coatings. Components like fracking plungers, wire drawing capstans, trolley festoon wheels, and rope pulleys operate in highly corrosive environments where advanced coatings are essential for maintaining performance and extending service life.

Turnaround time depends on the component type, coating method, and extent of wear or corrosion damage. Parkway-Kew provides full-service rebuilding and hardsurfacing with an emphasis on minimizing customer downtime.
