Abstract
The rapid growth of artificial satellites calls for sustainable deorbiting strategies to reduce space debris. This study combines hybrid demisable joints and physical vapor deposition (PVD)-based coatings to enhance satellite disintegration during re-entry. The DLR Institute of Structures and Design developed additively manufactured joints, integrating 3D-printed PEI and CF-PEEK materials with shape memory alloys (SMA) and compression springs, designed for high-altitude breakup and validated through tests and simulations. Meanwhile, the DLR Institute of Material Research employs PVD-based catalytic coatings on high-melting-point metals like V4A stainless steel to improve heat absorption and promote thermal failure. Magnetron sputtered Al, Si, Cr, or NiAl coatings, combined with a copper layer, encourage rapid oxide formation during re-entry. High-temperature lab tests and wind tunnel experiments validate these coatings' performance under extreme conditions. Together, these approaches offer complementary solutions for safer, more effective satellite demise.
