Combustion chamber

The combustion chamber of a supersonic spray system is the core component of the equipment. Its function is to generate a high-temperature, high-pressure gas flow—whose velocity can exceed 2,000 m/s—through the intense combustion of fuel and oxygen, thereby accelerating the spray material to supersonic speeds. Due to its prolonged exposure to extreme conditions—including temperatures exceeding 2,000°C, pressures in the megapascal range, and high-speed particle erosion—the combustion chamber has become one of the most vulnerable components in supersonic spray equipment.

The F1 complete set of nozzle electrodes for the anode and cathode is the key component for power supply and energy transmission in plasma thermal spraying equipment. As the starting point for plasma generation, the anode plays a crucial role in converting electrical energy into thermal energy. Its material must possess high electrical conductivity, excellent thermal stability, and good corrosion resistance.

The sealing ring of the plasma torch is a critical component that maintains the equipment’s seal and ensures the stability of the plasma arc. Its performance directly affects the equipment’s reliability and service life.

The ceramic ring of the plasma torch—also known as the “nozzle sleeve” or “insulating ceramic”—is a critical, wear-prone component that ensures the torch operates properly and maintains the stability of the plasma arc. Its performance and service life directly affect the precision, efficiency, and cost of plasma cutting and spraying.

In the field of thermal spraying technology in modern industry, supersonic spray gun barrels have become a key factor in enhancing coating quality and efficiency thanks to their unique flame-jet capabilities. These gun barrels not only generate high-speed jets through flame combustion but also demonstrate advanced technological features and broad application prospects in multiple aspects.

In the field of modern industrial thermal spraying technology, supersonic spray gun barrels have become an indispensable key piece of equipment in spraying operations, thanks to their unique ability to withstand extremely high temperatures. These gun barrels not only maintain stable operational performance at exceptionally high temperatures but also ensure that the sprayed materials are deposited onto the workpiece surface in a superior form, thereby producing high-quality, uniform, and durable coatings.

Anode for ceramic coating spraying equipment

In the high-temperature superconducting ceramic coating spray equipment system, the anode component plays an indispensable and crucial role. The anode is one of the key components in the entire spraying process, and its performance directly affects the quality and efficiency of the spraying.

Cathode with Plasma-Sprayed Nickel-Aluminum Alloy Coating

In the nickel mesh spraying process for hydrogen production via water electrolysis, nickel-aluminum alloy coatings play a crucial role, and 9MB plasma-spraying electrodes are indispensable in this process.

The 9MB spray-coated electrode boasts a sophisticated manufacturing process. It primarily employs a back-casting technique, in which copper alloy and tungsten alloy are fused together as a single unit via back casting. This manufacturing approach ensures a seamless weld between the two alloys, thereby achieving high strength and superior performance for the electrode.

Plasma spraying is an advanced technology that involves heating the spray material to a molten or semi-molten state and then using a high-speed gas flow to spray it onto the substrate surface, thereby forming a coating. The plasma torch anode plays a crucial role in this process.

The SG-100 spray gun is used for preparing plasma thermal barrier coatings with a bonding underlayer plus a ceramic topcoat.

The SG-100 plasma torch, widely recognized in the industry as a high-performance thermal spraying device, has become a key tool for preparing high-temperature protective coatings thanks to its high power output, flexible configuration, and proven process stability.

FST’s F1 plasma torch is renowned for its exceptional reliability and consistent coating quality, and is specifically designed to meet the demands of complex industrial applications. This torch adopts a modular design and offers two spray angle configurations—90° and 45°—to accommodate various workpiece geometries and coating requirements.
