Abradable Seal Coating and Anti-Wear Coating with Low Friction Coefficient for High-Temperature Gas Turbine Refurbishment

We provide professional seal and anti-wear coating services for gas turbine and steam turbine sealing components. Our coatings feature excellent abradability, a low friction coefficient, and stable high-temperature performance. These properties enable efficient clearance control, reduce friction and abrasion between mating parts, lower gas leakage, improve unit efficiency, and extend the service life of seal segments and seal rings.

The images below showcase our abradable and wear-resistant coatings applied across a full range of gas turbine components.

We offer a complete portfolio of abradable coatings and wear-resistant coatings covering gas turbine hot and cold section components. Our mature coating processes deliver reliable clearance-control solutions for shroud segments, seal rings, casings, and related sealing structures.

The abradable coating is designed for controlled rub-in. When the rotor and stator come into contact under transient operating conditions, the coating wears preferentially to safeguard costly blades from cracking or chipping, minimizing tip leakage and enhancing aerodynamic efficiency.

The wear-resistant coating provides superior anti-friction, anti-scuffing, and high-temperature erosion resistance, lowering material loss under cyclic thermal and mechanical loads.
