[Spraying Example] Clearance Control

The large-capacity plasma spraying of Shinko Metalcon is optimal for construction.

Thermal spraying is a surface modification technology that involves melting and spraying materials such as metals, ceramics, and cermets using various heat sources to form functional coatings on the substrate surface. In gas turbines used in aircraft and power plants, "ablative thermal spray coatings" are utilized for clearance control between the inner wall and the blades. These "ablative thermal spray coatings" require characteristics that are easily abradable and heat-resistant in high-temperature environments. As the blades rotate, the thermal spray coating collides with the inner wall and is abraded away, ensuring the proper clearance. The "ablative thermal spray coatings" require a substantial amount of thermal spraying time due to the large size of the products and the thickness of the coatings. The high-capacity plasma spraying by Shinko Metal Co., Ltd. is optimal for this application. [Features] [Ablative Thermal Spray Coating] ○ Clearance control between the inner wall of the gas turbine and the blades ○ Requires easily abradable characteristics and heat resistance in high-temperature environments ○ Ensures proper clearance by the rotation of the blades and the abrasion of the thermal spray coating against the inner wall ○ Products are large, and the thickness of the thermal spray coating is also substantial For more details, please contact us.
