Hydrogen Embrittlement And BakingWhat is hydrogen embrittlement and how is it prevented? Hydrogen embrittlement results from the simultaneous codeposition of the primary metal and hydrogen on the surface of the work piece (cathode). The hydrogen is available from the water in aqueous plating bath chemistries. Because the hydrogen atom is much smaller in size than the metal of the deposit, it is able to migrate into the crystal lattice of the basis metal, and reside interstitially between the individual metal atoms. The interstitial hydrogen can greatly amplify the stress of applied forces within the basis metal which can produce catastrophic fracture at loadings much lower than the typical yield strength of the material. Hardened steels (> 40 Rc) are particularly susceptible to this phenomena and as such are generally required to be baked after plating to protect against hydrogen embrittlement. Hydrogen codeposition can occur in the plating process either during the actual electrolytic deposition or during the cleaning and acid pickles preceding the plating bath. It is readily removed from the metal lattice by baking the product immediately after plating. The requirement for baking is a time-at-temperature cycle that is generally specified on the part print or within a plating specification. A typical cycle is to bake at 375ºF for 4 hours within 1 hour after plating. |
