Aircraft engine turbine blades demand cleanliness levels that leave no margin for error. Keertek’s lab demonstrated a validated ultrasonic process that removed manufacturing residues without affecting blade geometry or surface finish.
The blades, manufactured from nickel-based superalloy, carried machining oil and micro-particle contamination from the grinding process. For aerospace components, even sub-micron residue can cause hot corrosion at operating temperatures exceeding 1,000°C. Keertek deployed a precision multi-stage ultrasonic protocol with controlled-frequency modulation and a non-corrosive detergent specifically formulated for high-temperature alloys.
Post-cleaning particle count analysis confirmed compliance with AS9100 / NADCAP cleanliness thresholds. Surface profilometry showed no measurable change in blade profile — a critical outcome the customer required before signing off on a production-scale system.
