Evaluation of Hydrogen Embrittlement Value Due to the Electroplating of Steel Springs

Electroplating is a conventional process for spiral springs coating. One of the major problems in this process is considered to be the undesirable reaction leading to hydrogen embrittlement. Taking into account the application of springs in dynamic conditions, any ductile reduction may cause sudden and quick fracture. Unfortunately, hydrogen embrittlement in steel springs will not come along with any special signs. In addition, evaluation of hydrogen penetration and its consequent embrittlement requires very complex laboratory works, and is time consuming with little repetition due to its being affected by surface conditions as well as steel springs variations.
