Plasma spraying system is the core technical product of Lijia , which is specially designed to provide high-performance functional coating solutions for industrial fields requiring extreme thermal insulation, corrosion resistance or electrical insulation performance. The system utilizes the high-energy plasma arc generated by ionized inert gas to melt and accelerate the deposition of raw materials such as ceramic, alloy and composite materials on the substrate surface. Zhengzhou Lijia's plasma spraying system is known for its ability to handle refractory materials and complex geometries and is widely used in aerospace, energy, medical and semiconductor manufacturing industries.
The core of plasma spraying technology is the high-temperature plasma jet generated in the water-cooled spray gun. The main gas is ionized by a direct current arc to form a plasma plume, which heats the powder or wire to a molten or semi-molten state and accelerates the ejection to the substrate. Zhengzhou Lijia precisely regulates plasma parameters through its self-developed numerical control interface algorithm to ensure stable and repeatable coating quality, which is applicable to large-scale or high-throughput industrial scenes.
Zhengzhou Lijia's plasma spraying system is compatible with a wide range of materials and can meet diversified industrial challenges.
The modular design supports seamless integration of high-precision pulverized coal feeder, inert gas purification unit, real-time thermal imaging monitoring system and other auxiliary equipment.
Innovation is the key to leading plasma spraying technology of Zhengzhou Lijia. The company has patented a number of plasma gun designs, powder injection optimization, and in situ diagnostic tools to continuously improve process efficiency. Suspended plasma spraying technology developed in cooperation with scientific research institutions can realize nanostructure coating. With precision, durability and adaptability as the core, Zhengzhou Lijia plasma spraying system strengthens the global innovative status of the company in the field of advanced surface engineering.
