Measurement System for Hydrogen Absorption Due to Corrosion

Enables continuous/quantitative evaluation of the amount of absorbed hydrogen corresponding to environmental changes under actual service conditions!

Solution Point

Highly accurate, in-service measurement of hydrogen amount under atmospheric corrosion environments using a JFE original measurement system.
JFE's unique electrochemical cell structure enables measurement while installed on vehicles.
Possible to evaluate various types of steels, including coated (galvanized) materials, painted materials, etc.

Features 01

Expected Problems

Aren't you having the following problems?

• Want to compare hydrogen absorption in various parts of vehicles and other measurement targets.

• Want to know the hydrogen amount in the environment where the material will be used.

• Want to quantitatively compare the amount of absorbed hydrogen for different materials, such as UHSS, etc.

Features 02

Technology highlight

• Use of a compact hydrogen monitoring system that can be attached to actual vehicles (Fig. 1).

• Equipped with a reference cell for higher accuracy in measurements of hydrogen absorption (Fig. 2).

• Enables measurement at sub-zero temperatures by optimizing the internal solution.

• Enables stable long-term measurement in the vehicle moving environment (actual results: 2 years) (Fig. 3)

Features 03

Proposed Solutions (Examples)

Change of amount of absorbed hydrogen in vehicle moving environments.
