We can perform particle analysis tests
OIC offers several analytical methods for additive manufacturing powders and wear-generated particle assessment. Our sampling and evaluation procedures follow international test standards as described below.
We employ automated software to perform unbiased particle and powder assessment in a rapid, repeatable fashion. If custom particle analysis is required, our engineering team will develop modified sampling algorithms to suit your specific data needs. We pride ourselves on the ability to meet a customer’s specific needs with a wholly unique, tailored solution.

Wear of Implant Materials – Polymer and Metal Wear Particles
Similar to ASTM F1877 and ASTM F561, in this standard, samples of test fluid are digested and filtered for polyethylene, ceramic or metal particles resulting from wear, fretting, or corrosion. Filtered particles are coated and carefully examined using a scanning electron microscope (SEM), where high definition images are taken for custom automated particle characterization. Particle characterization may include measurements of area, aspect ratio, form factor, roundness, length, perimeter, ferret average, and equivalent circular diameter. Energy-dispersive x-ray spectroscopy (EDS) can also be performed for verification of elemental composition of particles. |

Characterization of Particles and Retrieval and Analysis of Test Fluids
Similar to ISO 17853, in these standards, samples of test fluid are digested and filtered for polyethylene, ceramic or metal particles resulting from wear, fretting, or corrosion. Filtered particles are coated and carefully examined using a scanning electron microscope (SEM), where high definition images are taken for custom automated particle characterization. Particle characterization may include measurements of area, aspect ratio, form factor, roundness, length, perimeter, ferret average, and equivalent circular diameter.
