CEIT-IK4 presents a very relevant expertise in the development and calibration of customised non destructive testing systems based on electromagnetic techniques. The previously mentioned offer is briefly described in the following points:
- In-service inspection of fatigue defects due to rolling contact fatigue (RCF) in rails.
- Surface and subsurface crack detection.
- Stress level estimation.
- Head checking, indentures, wheel burns, grinding marks.
- Grinding burns, control of surface integrity.
(e.g. gears, ball screws, bearings, camshafts, crankshafts)
