Detailed Environmental, Health, and Operational Benefits
(including Laser Ablation, Marking, and Welding)
1. Eliminate Harsh Chemicals
-
Laser Ablation: Replaces solvent‑ and acid‑based cleaning baths. No corrosive rinses or neutralization steps, so you eliminate VOC emissions and hazardous‑waste disposal fees.

High‑Pressure Turbine (HPT) Blades
Compressor & Fan Blades
-
Rolls‑Royce & University of Manchester: Research at Manchester’s Laser Processing Research Centre (2003–2013) led to automatic laser cleaning implementation for Ti alloys in compressor drums, achieving near‑100 % “first‑time right” welds and multi‑million‑pound annual savings by eliminating chemical baths [3](REF Impact Case Studies).
-
BAE Systems: Adopted the same process to replace chemical cleaning in airframe manufacture, further reducing waste and labor [4](Research Explorer).
1. Principles of Laser Cleaning
Laser cleaning uses focused laser pulses to remove contaminants—such as soot, oxides, CMAS (CaO–MgO–Al₂O₃–SiO₂), and grease—from turbine engine components without abrasive media or chemicals. Key mechanisms include:
-
Photothermal/Photomechanical Ablation: High‑peak‑power pulses (10–100 ns) induce rapid thermal expansion and shockwaves, spalling off deposits while preserving the substrate [1](ScienceDirect).
-
Wavelength Selectivity: Near‑infrared (1064 nm) Nd:YAG fibers exploit stronger absorption by contaminants versus metal, maximizing cleaning efficiency [2](SSRN).
-
Assist Gases: Argon or nitrogen (1–5 bar) flows purge ablated debris and inhibit re‑oxidation during cleaning [1](ScienceDirect).
2. Research on Turbine Blade Cleaning
2.1 High‑Pressure Turbine (HPT) Blades
Studies on nickel‑based superalloy blades coated with Y₂O₃‑stabilized ZrO₂ show that continuous‑wave fiber lasers (power density ≈ 7.96 × 10^6 W/cm²) effectively remove CMAS deposits under argon, delivering clean surfaces with controlled roughness [1](ScienceDirect). Integration of pulsed and continuous modes further improves oxide removal quality and throughput [2](SSRN).
2.2 Compressor & Fan Blades
Surface fouling on compressor stages degrades aerodynamics; laser ablation can strip oxide scales and debris without altering blade geometry. Early work demonstrated no microstructural damage when parameters are optimized, confirmed via SEM and X‑ray analyses [6](kones.eu).
