Metal material corrosion loss mapping method, metal material selection method, and metal material corrosion loss mapping apparatus

Abstract

A metal material corrosion loss mapping method includes creating a corrosion loss prediction map by using corrosion loss data including a use period of a metal material, a plurality of environmental parameters, position coordinates of the environmental parameters on a map, topographical data of the map, and a corrosion loss of the metal material. The metal material corrosion loss mapping method includes: an environment map creation step of creating an environment map at certain mesh intervals based on the environmental parameters, the topographical data of the map, and the position coordinates of the environmental parameters; a prediction request point input step; a similarity degree calculation step; a corrosion loss prediction step; and a corrosion loss prediction map creation step of creating a corrosion loss prediction map by coloring a prediction result of the corrosion loss at the prediction request point in the mesh.
