A blog on materials science, chemistry, and mechanical engineering

In some cases, these blog postings are cross posted with further explanation to make them more compelling to the less technical reader on Medium. The intent here is to share the capability, and more importantly the excitement of engineering and science.

Electron micrograph of anodic coating on aluminum alloy AA2219-T851 (between arrows) and in a pit caused by dissolution of Al2Cu which explains why anodizing aluminum causes fatigue.

Anodizing aluminum lowers fatigue strength in some alloys, which is related to extent of cold work during ingot breakdown.
