Enigneering - Materials

In the form of a techinical report describe each of the processes of degradation associated with the following metals, polymers , and ceramics.

Degradation of iron through rusting.

Degradation of polyethylene (polythene) though sunlight.

For the degradation processes listed below explain how the process affects the behaviour of the engineering material concerned. Present your finidings in the form of a techincal report.
