Unitek Technical Services is a reliable partner for nondestructive testing (NDT) services, with a deep expertise in the aerospace and defense industries. We can utilize magnetic particle inspection (MPI) to detect flaws in ferromagnetic materials. Our in-depth expertise, comprehensive approach and advanced technologies enable us to reliably perform these inspections, giving your operation the necessary level of quality assurance.
Magnetic Particle Inspection Methods We Use
We use several methods in the field of magnetic particle inspection, including dry particle and wet suspension techniques, which involve the application of both continuous and residual magnetization. Our MPI services can help identify flaws in various ferromagnetic materials, including iron, nickel and cobalt alloys.
The results of this inspection enable our technical specialists to assess part surfaces and subsurfaces to locate and assess discontinuities. Work with us to detect and correct defects through this NDT method before they can cause risk or compromise the product’s integrity.
Wet MPI
The wet method is ideal for detecting smaller defects on smooth surfaces and tight surface flaws due to the smaller particle size. We utilize highly sensitive particles in a liquid carrier to identify the finest fatigue cracks or defects for integrity in the most critical parts. Where identifying even microscopic defects is nonnegotiable, rely on us for the services you need.
Dry MPI
The dry method is more suitable for detecting larger defects and is commonly used in applications where the material’s surface is rough. We use this versatile and cost-effective solution to provide thorough insight into material quality without the need for extensive surface preparation.
Our Streamlined MPI Process

We deliver the clear, precise results your operation needs through a high-quality process. Here’s an overview of what it looks like:
- Meticulous preparation: We thoroughly prepare the surface to be inspected, eliminating contaminants that could lead to false readings, thereby ensuring the efficient use of time and resources.
- Advanced flaw analysis: We perform the chosen inspection to identify flaws. Afterward, we can analyze the characteristics and severity of any defects, providing a clear assessment that you can use to make informed decisions.
- Actionable reporting: After inspection, you will receive a clear, in-depth report. Our reports provide documented proof of compliance and offer detailed insights into any necessary actions to advance projects.
