Corrosion of steel, aluminum and other structural metals erodes the safety and financial stability of industries and countries alike. Fighting corrosion in ships, tanks, planes and equipment costs the Pentagon $22.9 billion a year. Corrosion costs advanced industrialized nations about 3.5 percent of GDP to replace damaged material and components, plus a similar amount due to lost production, environmental impact, disrupted transportation, injuries and fatalities.
While traditional corrosion protection has relied mostly on short-lived physically-bonded coverings of substrate surfaces, a new category of chemically bonded phosphate ceramics (CBPCs) can create a long-lived passivation layer that stops corrosion. This is further protected by a tough ceramic outer layer.
The limits of traditional corrosion protection
For generations, polymer paints have acted as a physical barrier to keep corrosion promoters such as salt water and oxygen away from steel and aluminum substrates. This works until the paint is scratched, chipped, or breached and corrosion promoters enter the gap between the substrate and polymer
