Title:
CORROSION TEST APPARATUS
Document Type and Number:
Japanese Patent JP2019109062
Kind Code:
A
Abstract:
To provide a corrosion test apparatus capable of quantitatively analyzing with high accuracy an amount of elements eluted from a metal material with progress of corrosion in a controlled corrosive environment.SOLUTION: A corrosion test apparatus includes: a preparation unit 1 for preparing a corrosive solution; a flow path 2 through which the corrosive solution flows; a recovery unit 3 for recovering the corrosive solution; an apparatus main body 4 having an installation unit 42 for installing a sample 41; a first pump 5 for sending the corrosive solution from the preparation unit 1 to the apparatus main body 4; and a second pump 6 for sending the corrosive solution from the apparatus main body 4 to the recovery unit 3, where the flow path 2 includes an introduction path 21, a first pulsation reducing path 22, a test flow path 23, a second pulsation reducing path 24, and a discharge path 25, in which the test flow path 23 includes a rising portion 23a, a laminar flow portion 23b and a falling portion 23c, and where the installation unit 42 can install the sample 41 so that the corrosive solution flows through the surface 41a in the laminar flow portion 23b.SELECTED DRAWING: Figure 1
