During engine overhaul, inspection quality is only as good as the surface preparation that comes before it.
Wet blasting is particularly effective because it combines water, abrasive media, and compressed air to clean components while controlling the impact of the abrasive. The water cushions the media, reduces heat, and prevents aggressive material removal.
The result is a clean, uniform surface finish without the risk of embedding contaminants or damaging critical surfaces.
This is especially important before NDT and dye penetrant inspection, where surface condition directly affects the reliability of defect detection.
When it comes to chosing the right wet blasting systems, our technology is tried, tested and installed in many of the world's leading MRO operatoins.
Our systems are designed to deliver consistent, controlled blasting conditions - essential when preparing critical jet engine components for inspection.
Key advantages include:
• Thorough contaminant removal - Removes carbon deposits, oxidation, oils, and previous inspection residues that could mask defects
• Uniform, non directional surface finish - Creates the ideal surface condition for dye penetrant inspection
• No risk of media embedding - The water based process keeps abrasive particles suspended and eliminates the chance of contamination
• Does not smear or peen over cracks - The cushioned action of the water suspended media helps avoid closing or masking fine surface cracks, allowing penetrant inspection to reveal genuine indications
• Process control and repeatability - Consistent blasting pressure, media flow, and slurry control help maintain reliable preparation across batches of parts.
• Suitable for precision components - Effective cleaning while maintaining dimensional integrity and protecting delicate features
In practice, surface preparation is much more than a cleaning step. It's a critical part of the inspection process. The better the preparation, the more confidence inspectors can have in the results.
For organisations involved in engine overhaul, the right preparation technology can make a measurable difference to inspection quality.
