Coating instead of chrome plating

Chromium plating is a traditional surface plating technology that has been used for more than 70 years. The chromium plating layer has high hardness, wear resistance, corrosion resistance and can keep the surface bright for a long time, and the process is relatively simple and the cost is low.

Coating for water turbine runner

The operation stability of hydroturbine generator is related to the efficiency and economic benefit of hydropower station. When the runner of Francis turbine runs normally, fatigue fracture or crack will occur on the runner blade due to water conservancy factors, which makes maintenance difficult, and the maintenance period is long and the process is tedious. Therefore, the failure of turbine runner blade has a very profound impact on the operation of generator set.

Coating of graphite boat bearing plate

A graphite boat is a graphite mold. The graphite die itself is a carrier, we can put the raw materials and parts we need to position or finalize the design together in the graphite die and sintered at high temperature. Graphite mold is made of artificial graphite by mechanical processing. So graphite mold sometimes become graphite boat, also known as graphite ship.

Thermal barrier coating

With the development of aviation, aerospace and civil technology, the use temperature of hot end components is more and more high, has reached the limit of superalloy and single crystal materials. Taking the heating parts of fuel turbine such as nozzle

Abrasion resistant coatings for gas turbines

In order to obtain higher energy efficiency and greater thrust, and heavy duty gas turbine engine turbine inlet temperature is as high as 1600 degrees above, only on the improvement of the performance of the materials and the improvement of structure design, has been unable to meet the rapid development of aviation engine and gas turbine industry needs

Abrasion resistant coating for inner hole

Zhengzhou Lijia has developed the spraying process and equipment for the inner hole of tungsten carbide with a diameter of more than 100mm. As the core of the supersonic flame inner hole spraying equipment, Lijia company uses HV-80D type kerosene supersonic flame inner hole spraying gun.
