Corrosion Resistance Improvement by Control of Corrosion Form

As an example of our developed alloys, there is an alloy that shows a layered corrosion form by adjusting the additive elements. As shown in Fig. 1, common alloys corrode in the plate thickness direction. However, as shown in Fig. 2, our developed alloy shows a layered corrosion form to delay corrosion in the plate thickness direction. The features of this developed alloy allow an extension of the durability time or weight reduction due to thinning of the tube wall by 10%.
