A fluorescent magnetic flux is applied to the surface of a ferromagnetic item. Magnetism is introduced to pull the flux into its surface. UV light makes the flux visible and reveals any indications on the surface of the item.
With this, we are able to confirm suspicions of hairline cracks found in gears, splines, shafts, pistons, housings, valve sections, and more that otherwise would not normally be seen by the naked eye.
Magnaflux inspections aid us in:
Troubleshooting mysterious weeping or leaking
Tracing possible causes for failures
Deciding if a part requires replacement
Some parts, such as port plates, require a special low-friction and wear resistant coating applied to their surface. This phosphate conversion coating, and the process for its application, is known as Parkerizing.
When this coating is compromised, it is removed and reapplied as shown below.
Surface is rough, worn, and scored.
Old parkerizing and imperfections removed
New parkerizing applied
Surface is now like-new, ready for installation
