Hardide plc (LON:HDD), the provider of advanced surface coating technology, has launched the first in a new range of ready coated and enhanced components with a 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 5 to 40 times when spraying carbide or metallic-based powders.
The extremely hard and homogeneous properties of the Hardide coating minimise 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. When spraying carbide powders, the Hardide coating extends the life of the nozzles by 5 times.
