How it is, that drill can be so weakly susceptible to damage, wing of the plane – fireproof, phone screen – watertight?
You „just” need to coat the element with an appropriate layer which is so thin, that even invisible for the eye. At the same time thanks to this thin layer the element receives completely new functionalities.
These kind of coatings are an effect of the sputtering process in an magnetic field, inside a vacuum chamber, with using plasma (an ionised gas).
The basis of this process (beside the vacuum) is an appropriate power supply.
