Anodic Etching -
An oxide conversion coating on a metal surface produced by making the metal the anode in an electrolyticbath. Usually applied to aluminum and titanium forcorrosion protection.
A solid solution of face-centered cubic iron and carbon. Occurs at elevated temperatures in all but heavilyalloyed steels or stainless steels, and decomposes on cooling to form the final microstructure.
Axial Load -
Force applied through the axis of a fastener or structure.
