Hardide Coatings has launched the first in a new range of ready coated and enhanced components with a JP-5000 4” copper nozzle used in High-Velocity Oxy Fuel (HVOF) thermal spray coating.

The tungsten/tungsten carbide-based Hardide chemical vapour deposition (CVD) coating is proven to extend the operational life of HVOF thermal spray copper nozzles by five to 40 times when spraying carbide or metallic-based powders. The ready coated nozzles include O-rings suitable to withstand the higher temperatures generated in longer periods of service.

“This is an extremely exciting new product development which offers significant performance, cost and environmental advantages to users of HVOF equipment,” said Steve Paul, interim CEO of Hardide Coatings. “By Hardide coating the internal diameter of copper nozzles used in thermal spraying, our enhanced component offers superior wear resistance and reduced pickup. This significantly extends the working life of the part thus improving productivity and reducing the spraying cost. We have had a lot of interest from OEMs and thermal spray companies in transforming the performance and durability of their HVOF spray equipment and we were pleased to ship our first production orders this week.

The extremely hard and homogeneous properties of the Hardide coating minimize pickup inside the nozzle when spraying metallic materials. This prevents material dislodging and forming a defect in the HVOF coating, therefore improving coating quality, reducing downtime and the cost of spraying. The life of the ready coated nozzles spraying metallic materials is extended up to 40 times compared to uncoated nozzles.
