Inspections by means of fluorescent magnetic particles are a very effective testing method to detect surface and sub-surface discontinuities in ferromagnetic materials. Bytest is equipped with a fluorescent magnetic particle inspection system meeting the most sophisticated needs of the aeronautical as well as other industries. The fluorescent magnetic particle testing method is subject to rigorous periodical inspections as required by the aeronautical industry.
Through a cycle of chemical etching, neutralization and subsequent de-embrittling thermal treatment, the Nital test can detect several surface anomalies (burns, re-tempering, lack and/or unexpected diffusion of carburization, etc.) occurring on steel parts as a result of processes including carburization, nitridation, induction hardening, or mechanical processes. Bytest performs Nital tests both for aeronautical and general industry applications.
