Hard Coating Services — Increased Wear Resistance

A hard coating is a wear-resistant surface layer applied to a component to improve durability, reduce abrasion, and protect against corrosion or surface breakdown. Parkway-Kew Corporation applies hard coatings such as tungsten carbide, ceramics, chrome oxide, and metal alloys using processes like HVOF, plasma spray, metallizing, fuse welding, and sub-arc welding, depending on the part’s operating environment.

Common hard coating types include tungsten carbide coatings for severe wear, ceramic coatings for high-speed or high-slip applications, chrome oxide coatings for excellent wear resistance, and nickel chrome alloy coatings for balanced durability and cost. Parkway-Kew also applies proprietary PK alloy systems through HVOF, plasma spray, metallizing, fuse welding, and submerged arc welding.

The best coating depends on the substrate, operating speed, load, corrosion exposure, surface finish requirement, and expected wear pattern. Parkway-Kew’s engineering team reviews these factors before recommending a coating alloy and application method. For example, PK-1500 chrome oxide may suit certain wire drawing applications, while tungsten carbide systems are often selected for harsher wear conditions.

Hard coatings are used across wire mills, oil and gas operations, shipping terminals, crane operations, heavy equipment, and industrial manufacturing. Typical candidates include wire drawing blocks, capstans, fracking plungers, sheaves, tuner rolls, step cones, guide devices, crane wheels, pulleys, and other components exposed to repeated wear, friction, corrosion, or surface fatigue.

Yes. Many worn parts can be rebuilt and recoated rather than replaced, depending on their condition and geometry. Parkway-Kew offers rebuilding, hardsurfacing, machining, grinding, and the Restore & Grind process for wire drawing blocks, which can repair only the drawline area and extend coating value before a completely new coating is required.

Service life varies by coating type, operating conditions, maintenance practices, material being processed, and the severity of abrasion or corrosion. Parkway-Kew’s coatings are designed to reduce frequent changeouts and improve component life. In some applications, proprietary coatings and rebuilt components have significantly outperformed original tool steel or OEM parts.

Parkway-Kew applies materials including tungsten carbide, ceramics, chrome oxide, aluminum, stainless, zinc, nickel chrome alloys, and proprietary PK coating systems. These materials are selected for specific performance needs, such as improved wear resistance, corrosion protection, reduced breakage risk, better surface finish, or cost-effective alternatives to solid ceramics and replacement parts.

Parkway-Kew Corporation is available Mondays through Fridays from 8:00 am to 5:00 pm. For quoting, it is helpful to provide part drawings, dimensions, base material, current wear issues, operating environment, and any required finish tolerances. The team can then evaluate the best coating method, alloy selection, machining needs, and rebuilding approach.
