Hardide Coatings, United Kingdom, 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 vapor 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 ready coated nozzles include O-rings suitable to withstand the higher temperatures generated in longer periods of service.
Steve Paul, interim CEO of Hardide Coatings commented: “This is an extremely exciting new product development which offers significant performance, cost and environmental advantages to users of HVOF equipment. 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 coated JP-5000 4” nozzle is the first in a range of Hardide ready coated copper nozzles of varying sizes and other OEM equipment which we intend to launch on an ongoing basis.”
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 so 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.
Morevover, the nozzle has to be exchanged less often which decreases the risk of breaking the water circuit, while lack of nozzle clogging reduces the likelihood of spits or unmelted agglomerations of powder becoming embedded in the spray coating thereby eliminating rework.
The Hardide coating is compatible with a wide range of coating materials used in HVOF processes, allowing for seamless integration with existing coating systems.
