Bubbles are key to new surface coating method for lightweight magnesium alloys

Tokyo, Japan – A team led by a researcher from Tokyo Metropolitan University has devised a new way of coating magnesium alloys to improve their corrosion resistance. Instead of costly, unwieldy, and slower coating techniques under vacuum, they used liquid-based chemical conversion coating with the addition of cavitation bubbles. The resulting thick coating helped improve corrosion resistance to chlorides and mechanical properties. The team’s new…
