Aviation sector

   In the aviation industry, engines have huge potential wear problems. Many moving parts in it are in contact with each other or some fixed contact parts suddenly change, which is a kind of

Mechanical parts. For this reason, the aviation industry has become one of the first industries to completely use thermal spraying. They apply thermal spraying to aircraft engines to optimize their working performance.

Most engine systems are composed of: fan blades, compressors, combustion chambers, high-pressure, low-pressure turbines and exhaust nozzles. The design of the engine includes a non-rotating system and two coaxial

The (stator) system is composed of a structural frame and a shell. The low-pressure rotating system is composed of blade discs, blades, low-pressure turbine discs, turbine blades and a connecting shaft. High pressure spin

It consists of a roulette/barrel, compression blades, turbine blades and a connecting shaft. The working environment of different parts of the engine is different, mainly depends on the task to be performed by the engine

The temperature ranges from 1095°C (2000°F), the speed is as high as 15000 rpm, and the bearing capacity of rolling bearings ranges from a few megapascals to more than 1720 MPa. As the rotor rotates and slides around the stator, the sliding

Ranging from an inch to a few tenths of an inch, or relative movement between components caused by vibration, will cause mechanical parts to collide with each other. Various components are also affected by spray materials.

Different spraying materials and spraying processes will be used to meet the design requirements of the engine. Textile industry

   In the textile industry, there are many elements connected to some fibers such as polyester, polypropylene, nylon, polyethylene, glass and carbon fiber, etc. These elements will be worn to varying degrees

Operational operation largely depends on the ability of these key components to resist fiber loss. Ceramic and tungsten carbide thermal spray coating can improve the durability of key components and improve

Wear.

Steel

    The extreme working conditions of the steel industry often cause different parts to wear. In the past ten years, we have done extensive research to improve steel

rate. In the past period of time, thermal spray coating has proven to be an effective solution, and now we are looking for a wider range of applications in this industry.

Boiler tube

    High temperature wear and corrosion of boiler tubes is one of the main reasons for plant maintenance and shutdown, and it is also a basic engineering problem of these equipment. The combustion process will produce some oxidation

A higher melting point than the boiler operating temperature. These particles will enter the exhaust port intact, resulting in continuous impact on the boiler tube.

    We always hear about corrosion of boiler tubes, such as overheating of boiler tubes. In particular, with the increasing demand for boiler tubes to work efficiently at high temperatures in modern factories

The rate of wear of the furnace tube. As the operating temperature increases, boiler corrosion and overheating problems will also increase significantly. In addition, the most widely used online cleaning of boiler tube overheating

Eclipse problem. Combining these working environments (overheating, erosion, corrosion), it is also very difficult to choose the correct thermal spray. If the coating or thermal spraying process is selected carelessly, the most

Steam turbine

    A steam turbine is a group of machines in which the mechanical action of solid surfaces cooperates with each other. These interactions will cause some wear such as: wear, high temperature corrosion, erosion, fretting

High-performance materials and thermal spraying process can solve these mechanical wear and can significantly improve the life and work efficiency. A popular thermal spraying method used now is called thermal insulation

Used in high temperature environment to increase the thermal effect and reduce heat loss.

Petroleum and natural gas

    For many industries, oil is indispensable, and it is also very important to the sustainable development of industrial civilization. The productivity of the petroleum and petrochemical industry

Less is our goal all the time. Thermal spray process can provide a superior solution to increase the life of parts. They can work in the most extreme environments. The application of thermal spraying to increase the entire oil and gas has been introduced many years ago and has become a reliable solution to the problem of wear. Tungsten carbide is a type often used in ball valves and

Coating material. This coating has high hardness and wear resistance, while also having excellent corrosion resistance. Tungsten carbide particles are embedded in the chromium matrix and are of different material properties

Water turbine

    Water turbines are divided into: bucket water turbines, axial flow turbines and Francis turbines. Usually wear corrosion and cavitation erosion. These hard particles will gradually wear down the leaves

The machine efficiency drops. Welding repair is very expensive and has a negative impact on power flow. Changzhou Shenli Thermal Spraying Technology Co., Ltd. has developed the HYDROCOAT series,

Ensure the superior performance of hydraulic turbine components.

Hydraulic cylinder

    Hydraulic cylinders are used in many different types of industrial fields, and at the same time they must maintain good performance in the harshest environments. Whether it’s sand, hot gas or

Will damage the surface of the oil cylinder and eventually lead to the destruction of the piston rod. Changzhou Shenli Thermal Spraying Technology Co., Ltd. pioneered the HYDROX series, which can ensure the performance of the cylinder.

    Hydraulic cylinders provide energy through liquid pressure, and the typical liquid is hydraulic oil. The hydraulic cylinder is composed of a cylinder body and a piston and piston rod group that runs back and forth in it.

The bottom of the tank is closed. When the piston rod is extended, it will face different working environments such as: fresh water or salt water, extreme high temperature, sand or mud, stones or other objects,

Impact. In order to protect the surface of the piston rod, hard chromium plating has been used in the industry for many years. Although its price is reasonable, it has very strict restrictions on thickness and size.

As the Environmental Administration has increased its management of its production process and the treatment of industrial wastewater, the cost of hard chromium plating has continued to rise. Therefore, find a

Coatings or processes that have better properties without negative impact are very important.
