Identifying corrosion initiation sites in aluminum alloys

Researchers at Tohoku University have developed a new technique to identify the initiation sites of a destructive process called pitting corrosion, which occurs when aluminum (Al) alloys are exposed to sodium chloride solutions. This advancement is expected to accelerate the development of Al alloys with improved corrosion resistance. Since Al alloys are widely used in transportation equipment, improving corrosion resistance means we can develop more durable automotive engines, suspensions, and transmissions.
