Spray Hard Coating Solutions

Among spray-applied coatings, plasma-sprayed ceramic coatings like chrome oxide (PK-1500) rank among the hardest, offering exceptional wear resistance for wire drawing applications. HVOF-applied tungsten carbide matrix coatings, such as PK-750, also deliver extremely high hardness and are widely used for heavy-duty, high-wear industrial components.

Toughness combines hardness with resistance to chipping and cracking. Tungsten carbide coatings applied via HVOF, such as PK-730 for fracking plungers, are considered among the toughest, balancing high hardness with impact resistance—outperforming solid ceramics, which can be brittle and prone to breakage or slippage under heavy loads.

We offer a full range of spray hard coating technologies including HVOF (High Velocity Oxygen Fuel), plasma spray, metallizing, submerged arc welding, and fuse welding. Each process is matched to the specific application, material, and performance requirements of components such as wire drawing blocks, capstans, and fracking plungers.

Restore & Grind fills and blends only the worn drawline area of a wire drawing block rather than requiring a full recoat, enabling 5-7 lower-cost repairs before a complete recoating is necessary. This significantly reduces downtime and extends the useful life of the component.

Yes. Parkway-Kew's proprietary finishing process for fracking plungers can correct up to .015 inches of out-of-concentricity with the clamping end, mimicking actual pump holding conditions to reduce vibration, scoring, and erratic pump performance.

Industries including oil and gas, wire and cable manufacturing, shipping terminals, and heavy equipment manufacturing rely on spray hard coatings to extend the life of high-wear components like plungers, drawing blocks, sheaves, festoon wheels, and rope pulleys.
