PtAl Coating Refurbishment and Platinum-Aluminide Coating Restoration with Uniform Thickness, Strong Metallurgical Bonding and High-Temperature Oxidation Resistance
Product Details
Uniform Thickness PtAl Coating Refurbishment
,Strong Metallurgical Bonding Platinum-Aluminide Coating Restoration
,High-Temperature Oxidation Resistance PtAl Coating Refurbishment
We deliver a one-stop, professional PtAl (Platinum-Aluminide) coating refurbishment service for turbine blades, vanes, and shrouds. The complete process covers old coating stripping, substrate inspection, surface treatment, high-quality PtAl diffusion coating, and professional heat treatment.
The renewed PtAl coating offers uniform thickness, strong metallurgical bonding, and excellent resistance to high-temperature oxidation and hot corrosion. It effectively protects superalloy substrates from extreme heat and thermal cycling damage, restores the component's original performance, and significantly extends its service life.
Consistent coating distribution across complex blade and vane geometries.
Reliable adhesion between the coating and the superalloy substrate.
Protects components under extreme operating temperatures.
Withstands aggressive corrosive environments in gas turbine operation.
Our PtAl coating stripping process completely removes failed, aged, and degraded platinum-aluminide coating from turbine blade surfaces using precise chemical and mechanical treatment.
After full coating elimination, Dye Penetration Inspection (PT) is performed to identify micro-cracks, thermal fatigue defects, and surface discontinuities on the superalloy substrates. Only blades confirmed defect-free proceed to recoating, ensuring high reliability, perfect bonding quality, and long-term service performance after refurbishment.
PtAl Coating Removal & Dye Penetration Inspection for gas turbine blades.
| Stage | Description |
|---|---|
| Coating Stripping | Chemical and mechanical removal of failed, aged, and degraded PtAl coating. |
| Substrate Inspection | Dye Penetration Inspection (PT) to detect micro-cracks, thermal fatigue defects, and surface discontinuities. |
| Surface Treatment | Preparation of the superalloy substrate for optimal coating adhesion. |
| PtAl Diffusion Coating | High-quality platinum-aluminide diffusion coating applied with uniform thickness. |
| Heat Treatment | Professional heat treatment to achieve strong metallurgical bonding and optimal coating properties. |
Only components confirmed defect-free after inspection proceed to recoating. This ensures high reliability, perfect bonding quality, and long-term service performance after refurbishment.
