Research direction:
with The Times, emphasized with high quality, high-tech equipment, multi-function material, solve the difficult problem of anti-corrosion anti-wear modern technology, power plant green desulfurization project progress.
The group discussed the thermal spraying:
The thermal spraying the surface strengthening and protection of the new technology, it in the surface modification technology plays an important role. The technology in our country began in s, 70 s form climate. Current, no matter in the equipment, materials, technology, scientific research, rapid development and the improvement in, has become a surface technology is an important part. Its development trend is: equipment (gun) to high energy, high enthalpy, high speed development; Materials to the serialization, standardization, commercial development direction, to ensure the high quality of coating multi-function needs; Technology, automation to mechanization development direction, such as computer control, robots operation, etc. Today, thermal spraying technology in all areas in the national economy have been widely used.
Economic efficiency: by spraying and surface strengthening or to protect or managment system, the double life of even a few times growth
