"Our coating is produced for the metal using a simple two- or three-step process to produce a thin film, structured by the bond between the compounds of the component," said chemist Toshifumi Sugama.
Corrosion resistance is essential for metals used in a wide range of applications, from appliances, aviation and power plants. Traditionally, compounds contain a toxic form of chromium, which has provided the best corrosion resistance. Scientists are looking to develop chromium-free alternatives that are unable to reach the thin layers desirable for many applications. "Ultra-thin coatings reduce the amount of material needed to provide corrosion resistance, thereby reducing costs," Sugama said.
