Abstract
Substrates, especially highly thermally expandable materials, such as plastics are adherently coated with a relatively soft layer comprising carbon and thereafter with a relatively harder layer of diamond-like carbon to provide coated articles that are abrasion resistant, electrically insulating, and resistant to chemical attack. If the substrate is transparent, the protectively coated article is transparent too.
