METHOD FOR PREDICTING TIME TO REDUCE METALLIC ELEMENT CONTENT

PROBLEM TO BE SOLVED: To predict a time to reduce a metallic element content in an anticorrosion coating. SOLUTION: The time to reduce the metallic element content within a metallic element diffusion treatment layer to 3-5 wt.% is predicted in a plane analysis by utilizing a behavior of an increase...

Zusammenfassung:PROBLEM TO BE SOLVED: To predict a time to reduce a metallic element content in an anticorrosion coating. SOLUTION: The time to reduce the metallic element content within a metallic element diffusion treatment layer to 3-5 wt.% is predicted in a plane analysis by utilizing a behavior of an increase in the ratio of an area occupied by an island-shaped low metallic element concentration phase distributed within the metallic element diffusion treatment layer.
