Picosun ALD has been proven to offer higher floor safety of articles in area

Picoson Atomic Layer Deposit (ALD) has been proven to be a viable possibility to guard surfaces in low Earth orbit towards atomic oxygen depletion. Objects carried into area require excessive materials survival attributable to numerous varieties of deteriorating situations similar to molecular oxygen publicity.

The researchers analyzed and analyzed a number of Picosun-supplied materials samples to make sure the suitability of the protecting coating for nuclear oxygen safety. As a part of the “Open Lab” check marketing campaign, the check was performed on the ESTEC TEC-QEE Laboratory LEOX facility. These campaigns are designed to offer new area enterprise entry to SMEs and institutes and to facilitate ESA’s distinctive area environmental testing amenities and collaborations with ESA’s analysis colleagues.

The check mimics the corrosive impact of molecular oxygen, for which satellites, together with the Worldwide House Station (ISS), are uncovered. Check outcomes on Kapton HN polyamide movie, silicone items and PCBs (printed circuit boards) protected with Picosun ALD coating clearly demonstrated the lower safety supplied by the ALD coating. The displayed low temperature (125 C) movie permits the coating of comparatively skinny (20 nm) numerous associated supplies. It’s stated that lowering the thickness of the ALD coating can stand up to extra deformation required for versatile supplies than thicker layers. Additionally, ALD coating might be utilized on 3D floor with excessive facet ratios. The evaluation performed by ESTEC included mass measurement, scanning electron microscope (SEM) inspection and measurement of thermo-optical properties, partially, earlier than and after testing.

“Atomic oxygen erosion has a serious affect on the collection of exterior supplies out there for spacecraft and satellites working on low Earth orbit. Picoson confirmed molecular oxygen resistance in ALD checks and types a protecting coating appropriate for excessive environmental situations, which additionally applies to versatile supplies at ESA Chemistry ESA” Adrian Tighe, Senior Supplies Engineer, defined the part.

“ALD is a complicated skinny movie coating methodology for ultra-thin, extremely uniform and conformal materials layers. It has already confirmed to be the coating resolution of selection in manufacturing in options and improvements that work in excessive environments. As we speak, they’re discovered in all places from the deep seabed to Mars, ”stated Juhana Costamo, VP, Picoson Group’s Industrial Enterprise Space.
