Non Destructive Testing

Non Destructive Testing (NDT) is an inspection method that does not permanently alter the article being inspected, making it a highly-valuable technique that can save both time and money in product evaluation, troubleshooting, and research.


Liquid Penetrant Inspection (LPI) is based on capillary action, where low surface tension fluid penetrates into a clean and dry surface. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed, and a developer is applied. The developer helps to draw penetrant out of the flaw allowing the indication to becomes visible to the inspector. Inspection is performed under ultraviolet or white light, depending upon the type of dye used.

Magnetic Particle Inspection (MPI) is used for the detection of surface and sub-surface defects in ferrous materials. An externally applied magnetic field or electric current is applied to the material. The iron oxide particles held in suspension are attracted to the surface field in the area of the defect and hold on to the edges of the defect to reveal it to the inspector. MPI can also be performed with dry particle allowing indications to be inspected under white light.


Temper Etch Inspection is typically performed by chemically etching the component’s surface with a solution of nitric acid in alcohol or water. The etched surface is examined visually to detect detrimental microstructural modifications (e.g. untempered martensite) that result from overheating during improper surface grinding.

Pre-Penetrant Etch uses either acid or caustic solutions to remove 0.0001″ to 0.0002″ of material from the parts surface. This will allow the penetrant inspector to properly evaluate any surface indications that may have been hidden during the manufacturing process.

Passivation is a final treatment used after LPI or MPI to create a passive layer that is free from all contaminants, such as machine metal, that may cause corrosion or failure throughout the life of the component.


Since 1948, we have provided the aerospace industry with highly innovative, superior quality, industry-leading plating, coating, special processes and testing services.

DCI Aerotech’s superior quality services are designed to help the aerospace industry battle and combat metal fatigue, oxidation, corrosion, and wear in extreme and hostile environments. These include extreme temperatures, humidity, and other harsh conditions that threaten the mechanical integrity of the aircraft.

DCI Aerotech’s highly skilled and trained technical staff works closely with leading aerospace component manufacturers and FAA repair facilities to create engineered surface solutions to combat extreme environments that meet and/or exceed industry standards.
