Abstract
A method for use in determining hydrogen embrittlement in a plated sample is provided. The method includes positioning the plated sample between a first holding member and a second holding member, moving the second holding member towards the first holding member to bend the plated sample, and applying a static load to the plated sample for a predetermined duration of time. The static load is applied by bending the plated sample to a distance between the first and second holding members that is a predetermined percentage of a baseline ultimate failure distance of the plated sample.
Claims20
A method for determining hydrogen embrittlement in a plated sample, said method comprising:
- positioning the plated sample between a first holding member and a second holding member;
- moving the second holding member towards the first holding member along an axis to bend the plated sample;
- and
- applying a static load to the plated sample for a predetermined duration of time, the static load applied by bending the plated sample out of plane with the axis when the first and second holding members are spaced an axial distance from each other, wherein the axial distance between the first and second holding members is selected to be a predetermined percentage of a baseline ultimate failure distance that causes a plurality of unplated samples to fracture.
A system for determining hydrogen embrittlement in a plated sample, the system comprising:
- a frame;
- a first holding member coupled to said frame;
- a second holding member coupled to said frame and configured to move relative to said first holding member along an axis;
- and
- a testing location defined between said first and said second holding members, wherein said testing location receives the plated sample and said second holding member moves towards said first holding member to apply a static load to the plated sample by bending the plated sample out of plane with the axis when said first and said second holding members are spaced an axial distance from each other, wherein the axial distance between the first and second holding members is selected to be a predetermined percentage of a baseline ultimate failure distance that causes a plurality of unplated samples to fracture.
