Additives for magnetic particle testing
In non-destructive material testing (NDT), magnetic particle testing (MPT ) is an established method for detecting cracks and material defects near the surface or open to the surface. In addition to magnetic powders, test oils or finished suspensions, additives also play an important role in magnetic particle testing. They are used to optimize and stabilize the test equipment used for testing - for consistent quality, improved visibility and reliable test results.
What are additives for magnetic particle testing?
Additives are agents that are added in small quantities to suspensions or carrier media in order to specifically influence or restore certain properties. In magnetic particle testing, for example, they are used to
- reduce foaming of the suspension,
- improve corrosion protection,
- increase the wettability,
- or to increase biostability.
They therefore make a decisive contribution to process reliability and test equipment stability - especially during continuous operation or longer periods of use of the consumables.
Advantages of additives in MPI testing processes
The targeted use of additives for magnetic particle testing can bring numerous advantages:
- Consistent indication quality even over longer periods of use
- Extension of the shelf life of suspensions
- Simple adaptation of consumbales to changing test conditions
- Avoidance of unnecessary disposal of used consumables
- Maintaining conformity with standards, e.g. ISO 9934
