HVOF JP5000 Metal Components
High-Velocity Oxygen Fuel (HVOF) JP5000 is an advanced thermal spray coating technology used to produce high-performance metal components with exceptional durability, wear resistance, and corrosion protection. The HVOF JP5000 process involves spraying molten or semi-molten materials at extremely high velocities onto a substrate, creating a dense, well-bonded coating that significantly enhances the performance and lifespan of critical parts.
Key Features of HVOF JP5000 Metal Components:
Superior Wear Resistance:
The coatings produced by HVOF JP5000 exhibit excellent resistance to abrasion, erosion, and sliding wear, making them ideal for components operating in harsh environments.
High Bond Strength:
The high-velocity impact of the sprayed particles ensures strong adhesion to the substrate, resulting in coatings that are less prone to delamination or peeling.
Corrosion Protection:
HVOF JP5000 coatings provide outstanding resistance to corrosion, even in aggressive chemical or high-temperature environments.
Dense Coating Structure:
The process creates coatings with low porosity and high density, ensuring superior mechanical properties and long-term performance.
Versatility:
HVOF JP5000 can be used with a wide range of materials, including carbides (e.g., tungsten carbide-cobalt), metals, and alloys, making it suitable for diverse industrial applications.
Applications of HVOF JP5000 Metal Components:
Aerospace: Turbine blades, engine components, and landing gear parts.
Oil & Gas: Pump shafts, valves, and drilling equipment.
Automotive: Engine components, piston rings, and transmission parts.
Power Generation: Turbine blades, boiler tubes, and heat exchangers.
Industrial Machinery: Wear-resistant coatings for rollers, shafts, and seals.
Advantages of HVOF JP5000 Technology:
Extended Component Lifespan: Reduces downtime and maintenance costs by enhancing the durability of critical parts.
Cost-Effective: Provides a cost-efficient solution for improving the performance of high-value components.
Customizable: Coatings can be tailored to meet specific operational requirements, such as thickness, hardness, and surface finish.
Why Choose HVOF JP5000 Metal Components?
Proven Performance: Trusted by industries worldwide for its reliability and effectiveness.
Advanced Technology: Utilizes state-of-the-art thermal spray techniques to deliver superior results.
Expert Support: Backed by technical expertise and comprehensive service to ensure optimal outcomes.
The JP-5000 HVOF gun
The JP-5000 HVOF gun is designed for the liquid-fuel HVOF spray process and can be considered as the benchmark for HVOF guns. Robust, long-lasting components are used throughout, ensuring long spray runs and low maintenance requirements.
The JP-5000 liquid-fuel HVOF gun is a proven design using economical kerosene fuel to generate high quality, dense, wear resistance and/or corrosion-resistant coatings. Coatings can be applied very thick and exhibit favourable compressive stresses that increase bond strength and coating performance. The JP-5000 design is simple, rugged, featuring durable, long service life components that can withstand the harshest industrial spray environments, reliably and repeatedly.
The JP-5000 is designed for liquid-fuel (kerosene) and oxygen operation. Fuel and oxygen are fed into the gun, atomized by the coaxial stabilizer and ignited in the combustion chamber, resulting in a supersonic flame. Spray powder from the powder feeder is fed radially into the supersonic flame through two powder ports positioned directly after the combustion chamber. The spray stream is accelerated through a converging/diverging nozzle several times the speed of sound. The spray particles are heated to a molten or semi-molten state and propelled at high velocity, impacting the coating surface in a plastic state.
Several barrel lengths (4, 6 and 8 in) are available to optimize the dwell time of the spray particles in the jet stream while keeping the dwell time of the particle to a minimum.
Liquid fuel HVOF offers certain advantages over gas fuel processes, such as the easy availability and handling of fuel, and higher energy density associated with these fuels. The increased quantity of heat available results in denser coatings with higher bond strengths.

Advantages of plasma spray nozzles and electrodes produced by our company:
1. Our company has been engaged in the production of pure tungsten and tungsten alloy materials for many years, and has an in-depth understanding of the structure and properties of materials. For the tungsten electrode used in plasma spraying electrodes, based on our full understanding of the application, we have made more improvements and treatments to the material structure to meet the material requirements of plasma spraying. By densifying the tungsten electrode, a finer, more uniform grain structure is formed. The modified tungsten alloy has relatively high hardness and density, fast arc starting, excellent resistance to arc burning loss, and long life.
2. Our company's plasma spraying electrodes and nozzles use unique back-casting technology to achieve seamless bonding between tungsten and copper. The bonding strength can be as high as 127MPa, while the traditional bonding strength is less than 100MPa. Compared with traditional brazing, joints made by back-casting have higher bonding strength between tungsten and copper, larger contact area, more uniform resistance, and stronger heat dissipation ability, making the nozzle and electrode more stable and more durable as well as long service life.
3. We produce tungsten electrodes of different materials (good arc starting performance and ablation resistance). Based on customer usage conditions, we can provide more suitable materials for customers to choose.
| Material | Impurity content (%) | Electron work function (eV) |
| Lanthanum tungsten | <0.2 | 2.8-3.2 |
| Cerium tungsten | <0.2 | 2.7-2.8 |
| Thorium tungsten | <0.2 | 2.0-3.9 |
4. Based on the research and analysis of plasma spray guns, the electrodes and nozzles produced by our company can perfectly adapt to the original spray guns, and no additional adjustment of spraying parameters is required during replacement. We have a complete product series, and the plasma spray electrodes and nozzles we produce can be widely used in F4, 9M, SG-100 and other spray guns of Metco, GTV, FST, AMT AG, Praxair and other companies.
5. We have rich experience in producing various cathodes and anodes, which can be customized and processed according to customer samples or drawings. We can also provide semi-finished products with seamless combination of tungsten and copper.
We can ensure our all products which are seamless bonding,no gas foam generating,and assure concentricity,if any defect has been found which are due to our cause,we can replace them for free and send you along with shipment for next time.
