In order to protect objects, which are made of steel or metal, they are coated with corrosion resistant materials such as rubber, synthetics or enamel.
The protective coatings must be tight, that is, free of pores, cracks or embedded foreign objects, to keep aggressive materials from the carrier material that is in danger of corrosion. Fine pores or cracks cannot be entirely avoided in any coating process.
With the POROSCOPE® HV40, even pores and cracks, not visible to the eye, can be discovered and counted in electrically non-conducting protective coatings.
