ABSTRACT:
The metal edge of a ski is coated with carbon by creating an electrical voltage differential between a relatively moving carbide electrode and the metal edge of the ski spaced therefrom such that an electrical arc passes from the electrode to the metal ski edge across the space. The electrical arc carries carbide from the electrode and deposits it on the metal ski edge.
