Fluorescent Penetrant Inspection

Fluorescent Penetrant Inspection

 

a method of capillary flaw detection, in which the defects are found using indicator substances (penetrants) applied to the surface of the article being tested. The composition of the penetrants is based on phosphors.

Orlando, FL, April 14, 2018 --(PR.com)-- FinnSonic, the leading expert in ultrasonic cleaning and fluorescent penetrant inspection, and DAES Representation a leading aerospace worldwide provider, announced during the celebration of MRO Americas 2018 the renewal of their partnership.
The first method used to identify surface defects is known as fluorescent penetrant inspection. Fluorescent liquid is highly sensitive to black light when it is applied to a clean surface of a metal part.
Chemetall has introduced a new water-based penetrant for ecofriendly and process efficient fluorescent penetrant inspection. Britemor 921 (W) enables bright and crisp indications on a wide range of materials, including ferrous and non-ferrous metals, and non-porous ceramics, thanks to its very low fluorescent background and excellent wash characteristics.
Soundness, as verified by nondestructive testing, was established per AMS2175, "Classification and Inspection of Castings." Fluorescent penetrant inspection per ASTM E1417 was required for 100% of the items produced, but radiographic inspection was specified on a sampling basis to provide cost-effective process control of key variables in melting, feeding, and solidification.
These include extensive non-destruction testing such as magnetic particle inspection and Zyglo[R] fluorescent penetrant inspection. "In addition to a full complement of inspection blocks, gages, micrometers, etc., we also have two CMMs and a borescope," adds Ohlinger.
After an engine or engine component has been assigned to Aviall for repair, the staff usually cleans the parts; visually inspects them; and then subjects them to fluorescent penetrant inspection, a dimensional inspection, and eddy-current inspection for detecting cracks.
Fluorescent Penetrant Inspection (FPI), which applies a fluorescent dye to the blade to show where cracks are, has been the most widely used method; however, FPI is time-consuming, costly, and subject to human error.

The former offers widely-proven non-destructive testing (N DT) and fluorescent penetrant inspection (FPI) systems, which often interface directly with Plasticraft technology.
Small mi-croshrinkage on a sealing face was being revealed after machining and fluorescent penetrant inspection. Subsequent review of the simulations using more sensitive criteria duplicated the microshrinkage found in the part (Fig.
