Corrosion Fatigue of Anodized Aluminum 7075-T73 in Salt Ladened Humid Air.

Abstract

Corrosion fatigue of A17075-T73 anodized by various methods has been measured in salt laden moist air. Principal results are: anodization caused a reduction in fatigue life irrespective of the thickness or type of anodization; a correlation of alumina density with fatigue life was not found; and reduction of fatigue life in environment is attributed to crack growth of microcracks both present and/or initiated in the anodized coating. Details of fatigue environmental chamber and statistical analysis of the data are given in appendices. (Author)
