Detection of hairline cracks in bearings for medical devices

All components of medical devices are subject to very stringent safety and quality requirements. For example
is the slide bearing used in precision Xray equipment: The flawless functioning of these bearings depends on,
among other things, the quality of their surfaces. All defects in those surfaces, even the finest hairline
cracks, must be ruled out – this a major challenge during  inspection.

The Bearings, such as those used for the moving X-ray tube are actually gliding on a thin film of liquid. If
the surfaces have any damage at all, perfectly free movement cannot be assured for the service lifetime.

Technically, such cracks near the surface are difficult to detect, as optical inspection methods very quickly
reach their limits with fine hairline cracks. However, measuring the electrical conductivity of the material
provides a simple and quick way to detect even tiny fissures.

This method is very sensitive to structural inconsistencies.

FISCHER’s mobile handheld instrument SIGMASCOPE®

SMP10, used together with the probe ES40, non-destructively measures the electrical conductivity of nonferrous metals
rapidly and precisely using the phase-sensitive eddy current method, which produces exactly the right conditions
required for crack detection.

To check a surface for cracks, the probe ES40 is passed over the surface of the sample in free-running mode. Eddy
currents are formed in the material, which are in turn recorded by the probe and converted to a signal in the
instrument. In the case of the bearings we examined as a test, the conductivity measured was in the range of
18.3 MS/m, with very low variation. Any hairline cracks in the material will hinder the spread of the eddy
currents – even the very finest, optically invisible faults. In practice, when the tested bearings showed a value
of e.g. 14 MS/m, that would clearly indicate that a crack had been found by means of electrical conductivity.

The probe ES40 has a range of measurement frequencies (60-480 kHz), making it suitable for different material
thicknesses. Using a lower measurement frequency results in the eddy current field penetrating deeper into
the sample material.

The measurements on the bearings described above were carried out using the probe’s highest frequency of 480 kHz,
thus looking specifically for damage in the material near the surface. For use on tiny parts, the optional
probe ES24, which has a smaller measuring head than the ES40, is recommended.

by means of the phase-sensitive eddy current method

For the detection of fine hairline cracks in medical X-ray equipment, measuring the electrical conductivity
with the SIGMASCOPE® SMP10 from FISCHER is an excellent solution. And between the two probes
ES40 and ES24, a wide variety of part geometries can be accommodated, completing the ideal system for
this purpose.
