Abstract
Slippery liquid-infused porous surfaces (SLIPS) provide a durable approach to mitigate icing. In this study, SLIPS were fabricated on laser powder bed fusion (L-PBF) printed Ti6Al4V and AlSi10Mg alloys by combining native surface roughness with nanosecond laser texturing. The laser-induced microgrooves enhanced lubricant retention, while fluorosilane functionalization enabled silicone oil infusion to form a stable, low-adhesion interface. The resulting SLIPS exhibited high water repellency, with static contact angles of approximately 110–115° and sliding angles below 10°. Ice adhesion strength was significantly reduced from 370 to 460 kPa for untreated and laser-textured surfaces to ∼65 kPa for Ti6Al4V and ∼ 90 kPa for AlSi10Mg after lubricant infusion. In addition, the freezing delay time increased to approximately 1200–1300 s on SLIPS, compared to ∼550–630 s for non-infused surfaces. The coatings maintained low ice adhesion under repeated icing/de-icing cycles and mechanical abrasion. This work demonstrates a scalable method for integrating SLIPS with 3D-printed metals, highlighting a practical route toward durable anti-icing surfaces for aerospace, marine, and energy applications.
