Hvof Grading Wheel Coating Machinery - China

The HD-8000 equipment of Zhengzhou Lijia Thermal Spraying Machinery Co., Ltd. is a remarkable supersonic flame spraying system that demonstrates exceptional performance in the thermal spraying domain.

It employs aviation-grade kerosene as the fuel source and oxygen as the oxidizing agent, creating an extremely secure combustion pattern and minimizing the safety hazards during the operation process.

The spray gun of this equipment has an ingenious design, inspired by the principle of rocket engines.

The peak pressure inside the combustion chamber can reach up to 150psi, and it is capable of generating a supersonic flame stream with a velocity exceeding 2000m/s.

The output power is robust and can be adjusted steplessly to satisfy various spraying demands.

The spray gun utilizes radial powder feeding technology, which allows the powder to be evenly dispersed within the flame and fully melted, significantly boosting the coverage efficiency and the quality of the coating layer.

The HD-8000 system is characterized by a scientific and well-thought-out design.

By maintaining the temperature within a rational range and emphasizing the increase in velocity, the prepared coating exhibits high bonding strength and density, and the surface shows compressive stress, greatly enhancing the coating's durability.

The system adopts a fully closed-loop fuel flow design, coupled with modular and high-performance PLC control, making the operation straightforward and secure.

Regarding performance indicators, the particle velocity produced by its combustion reaches as high as 1100 meters per second, far surpassing other similar High-Velocity Oxygen-Fuel (HVOF) systems.

The thickness of the sprayed coating can exceed 10mm (for the compressive stress coating), and it has excellent microhardness.

Taking the HV-80 type spraying of the WC-Co coating as an instance, the microhardness is as high as 1450, whereas that of other gas HVOF spray guns is merely between 900 and 1100 - The bonding strength of the coating can reach 90MPa, and the porosity is less than 1%, reaching the international leading standard and having been verified and certified by authoritative domestic and international institutions.

This equipment enjoys a broad scope of applications and plays a crucial role in numerous industries, including the medical, aviation, automotive, and cookware sectors.

For example, in the aviation field, it can be utilized for spraying engine parts to enhance the parts' high-temperature resistance and wear resistance; in the automotive industry, it can carry out surface treatment on key components to extend their service life.
