Magnetic particle testing is a non-destructive testing method in order to detect surface and sub-surface irregularities in ferrous parts. As a first step a magnetic field is put into the part tested. The magnetization can be direct (electrical current is passed through the test object) or indirect (magnetic field is applied from an outside source). Ferrous iron particles (dry / wet suspension) are then applied to the part. In case of an area of flux leakage, the particles are attracted to this area and form an ‘indication’. The inspection can be performed under UV(A) or white light, depending on the type of MT product used: fluorescent or black magnetic ink.
With Ardrox® non-destructive testing (NDT) products we are well acquainted with the high standards in the aerospace field for many years. Additionally, the high quality of the available NDT products and services has also convinced the automotive industry and its component supplier market, general industry and all areas of energy generation and transportation. The multiple approvals of our Lumor® and Supramor® MT products are proof of this.
We support your processes continuously and competently. Trained experts are globally available for your questions at all levels regarding your process. This broadly diversified competence is also requested elsewhere: Chemetall experts, for example are members of various committees which take part in discussions to define continuous improvements, standards, rules and norms concerning non-destructive material testing.
