Abstract
The hydrogen charging device includes an anode material that can be accommodated in a through-hole provided inside a test specimen in a state of being separated from an inner peripheral surface of the through-hole, a circulation path and a liquid pump that circulate and supply an electrolytic solution into the through-hole, and a direct-current power source that applies a minus voltage to the test specimen and a plus voltage to the anode material.
Claims8
A hydrogen charging device, comprising:
- a circulation path and a liquid pump that circulate and supply an electrolytic solution into a through-hole provided inside a test specimen;
- an anode material capable of being accommodated in the through-hole provided inside the test specimen, in a state of being separated from an inner peripheral surface of the through-hole;
- and
- a direct-current power source that applies a minus voltage to the test specimen, and a plus voltage to the anode material.

A rotating bending fatigue testing machine, comprising:
- a pair of tubular shaft members coaxially disposed to face each other to rotate a test specimen in a state of respectively gripping end portions of the test specimen having a through-hole opening on both end surfaces;
- bending means that applies a bending moment to the test specimen;
- driving means that rotates the test specimen in a state where a bending moment is applied by the bending means;
- and
- a liquid pump and a circulation path that circulate and supply an electrolytic solution from one of the tubular shaft members to another one of the tubular shaft members via the through-hole of the test specimen gripped by the tubular shaft members.
