Coating Products & Solutions

Common industrial coating types include HVOF (High Velocity Oxygen Fuel) sprayed carbide coatings, plasma-sprayed ceramic coatings, metallizing, submerged arc welding overlays, and fuse welding coatings. Each type offers different hardness, wear resistance, and finish qualities suited to specific applications like wire drawing blocks or fracking plungers.

Coating additives are supplementary materials or alloying elements blended into a base coating formulation to enhance specific properties such as hardness, crack resistance, or bonding strength. In hardsurfacing applications, additives like chromium, boron, or carbide particles are incorporated to improve wear resistance and surface finish quality.

Common coating materials include tungsten carbide for extreme wear resistance, nickel chrome for corrosion protection, chrome oxide ceramics for the most wear-resistant surfaces, and specialized alloy blends like PK-503 and PK-200 that provide hardness while balancing crack resistance for demanding industrial environments.

Hardsurfaced wire drawing blocks coated with tungsten carbide matrix or ceramic coatings significantly outlast standard uncoated blocks, often lasting years longer under continuous operation. The exact lifespan depends on wire material, drawing speed, and coating type, but properly coated blocks dramatically reduce changeout frequency and downtime.

Restore & Grind is Parkway-Kew's proprietary repair process that fills and blends only the worn drawline area of a wire drawing block rather than fully recoating it. This allows 5-7 lower-cost repairs before a complete recoating is needed, substantially reducing maintenance costs and equipment downtime.

Oil and gas, wire drawing, shipping terminals, and heavy equipment industries benefit most, using Parkway-Kew's coatings on fracking plungers, wire drawing blocks, festoon wheels, and rope pulleys to reduce wear, downtime, and replacement costs.
