Chrome Oxide Ceramic Coatings

Yes, chromium oxide (Cr₂O₃) is classified as a ceramic material. When applied as a thermal spray coating, it exhibits the hallmark ceramic properties of extreme hardness, high-temperature stability, and superior wear resistance. Parkway-Kew's PK-1500 Chrome Oxide is a plasma-sprayed ceramic coating recognized as the most wear-resistant option available for wire drawing block applications.

PK-1500 is Parkway-Kew Corporation's proprietary plasma-sprayed chrome oxide ceramic coating, recognized as the most wear-resistant ceramic solution for wire drawing blocks. It is applied using plasma spray technology, delivering a hard, dense surface that withstands severe abrasion, reduces block wear, and extends the operational lifespan of wire drawing components significantly compared to alternative coatings.

Plasma spray chrome oxide, like PK-1500, delivers the highest wear resistance among ceramic coating options for wire drawing blocks. Compared to HVOF tungsten carbide or metallizing coatings, chrome oxide ceramic is ideal for applications with extreme abrasive contact. It offers a cost-effective alternative to solid ceramics, eliminating breakage and slippage problems common with solid ceramic blocks.

Yes. Parkway-Kew's Restore & Grind process allows worn wire drawing blocks, including those with ceramic coatings, to be rebuilt and reconditioned. This proprietary service fills and blends the drawline wear area, enabling 5 to 7 cost-effective repairs before a full recoating is required. This dramatically reduces total cost of ownership and operational downtime for wire mills.

Chrome oxide ceramic coatings are primarily used in the wire drawing industry for coating blocks and capstans used in ferrous, copper, and aluminum wire drawing. They also benefit heavy industrial sectors where components face constant abrasive wear, including manufacturing operations involving guide devices, sheaves, tuner rolls, and step cones that require maximum surface hardness and longevity.

The best coating depends on your wire type, drawing speed, and load conditions. Parkway-Kew provides technical consultation and presentations to help customers select between chrome oxide ceramic (PK-1500), HVOF tungsten carbide, metallizing, or submerged arc options.
