metal velcro

 learning from velcro, or geckos' feet perhaps, micro-sized projections on the surface of metals are made to strengthen adhesions to composite materials like glass and plastics. this technique could also encourage bone to grow onto artificial hips and make heatsinks of any size. the projections are made by melting the surface of the metal with an electron beam and pushing the molten metal to a point from several directions until a projection is achieved. New Scientist has the story. |
