The Invisible Micro-Lightning: How Raindrops Act as Miniaturized Electrical Discharges to Corrode Protected Surfaces
Executive Overview For centuries, human engineering has operated under a straightforward, mechanical consensus regarding how rain damages protected surfaces. The traditional model dictates a slow war of attrition: rainwater acts as a solvent, transporting dissolved salts and corrosive acids across exposed materials, while the relentless, micro-abrasive drumming of falling droplets degrades protective polymer films, paints,…
