The preeminent theories for hydrogen damage are based on pressure, surface adsorption, decohesion, enhanced plastic flow, hydrogen attack, and hydride formation. The specific alloys covered are iron-base, nickel, aluminum...

The applicability of these methods is determined by the configuration of the parts, the surface finish required, and the allowable loss of gage or dimension. However, abrasive cleaning can remove some metal and degrade surface finishes...

.... Contemporary with the development of alloys, from 1960 to the present, was the realization that coatings would be needed to protect component surfaces from degradation owing to gaseous and deposit-modified corrosion. Aluminide diffusion coatings were applied with increasing frequency, and MCrAlY-type (where M...

For a variety of reasons, the authors of this article propose reexamination of materials if degradability was assessed only by visual procedures (for example, fungal growth on surface) or if the mass balance of starting material and products was not established. On the other hand, it is highly likely...
