Your (every) engine manufacturer masks off areas that they dont want to be hardened with a copper oxide. There is something that has changed in the aeroshell that causes the copper to wash off.. there is no harm as there is regular steel or iron left behind.... all it is is a coating for manufacturing processes. As far as the lycoming rep is concerned, there are no copper wear parts in these engines.
