PtAl Coating Refurbishment with High-Temperature Oxidation Resistance and Hot Corrosion Resistance for Uniform Thickness Platinum-Aluminide Coating Refurbishment

We provide a one-stop professional PtAl (Platinum-Aluminide) coating refurbishment service for turbine blades, vanes, and shrouds. The full process includes old coating stripping, substrate inspection, surface treatment, high-quality PtAl diffusion coating, and professional heat treatment.

The renewed PtAl coating features uniform thickness, strong metallurgical bonding, excellent high-temperature oxidation resistance, and hot corrosion resistance. It effectively protects superalloy substrates from extreme high temperature and thermal cycling damage, restores component original performance, and greatly extends service life.

We specialize in PtAl coating refurbishment for gas turbine rotor blades. The full process includes old PtAl coating stripping, substrate cleaning, defect inspection, precise surface preparation, advanced platinum-aluminide diffusion coating, and standardized heat treatment.

The refurbished PtAl coating features uniform layer thickness, excellent metallurgical bonding, and no peeling or voids. It significantly improves the blade's resistance to high-temperature oxidation, hot corrosion, and thermal fatigue under extreme turbine operating conditions.

This service fully restores blade original protective performance, extends service life, and reduces operational and replacement costs.
