Magnetic Particle Inspection To Detect Material Imperfections

Cracks are an unfortunate reality when working with metals. Cracking during the heat treating process can be caused by several factors. Whether it’s the heat treating application itself or material imperfections, cracks can slow down your manufacturing process. However, using magnetic particle inspection can make heat treating your parts more reliable and defect free. This inspection process is a non-destructive inspection method used for the detection of defects in ferrous materials, capable of detecting surface and near-surface cracks and problem areas.

The Magnetic Particle Inspection Process

We begin by using a strong electric current, which creates a magnetic field within steel or iron parts. After we apply a fluid containing special particles coated in fluorescent dye, defects that are on or near the surface will appear.

At Zion, we perform magnetic particle inspection along with our induction hardening setups, and other processes. Because we specialize in induction heating, our customers benefit from the integrated heat treating solutions that we provide to many industries.

Although we specialize in high volume production runs, we also have an induction development lab available for prototype and process development work. If you have large and unique part configurations such as rolls/shafts and gears, we can accomplish this with power supplies that range in size from 5 kW to 300 kW and in frequency from 1 kHz to 450 kHz. The high-quality and on-time work has given Zion it’s excellent reputation as a commercial heat treating company within our region.

Our team looks forward to working with you on specific parts that may be a problem currently or that you may have had a problem with cracking in the past. Our team would be happy to evaluate the project and help offer a solution.
