Abstract

Pulsed arc-discharge deposition has been used to prepare diamond-like carbon (DLC) films on various substrates. Both direct and curved plasma methods have been used. Coatings with excellent tribological properties and good adhesion have been demonstrated. The coefficient of friction of diamond-like films against a Si3N4 ball was between 0.045 and 0.084 which is an order of magnitude smaller than for most other materials. The corresponding wear coefficient was between 0.5 × 10-16 and 1.7 × 10-16m3N m-1. The diamond-like films produced using mass-separated ion beams seem to be similar in structure and properties except that the arc-discharge deposited films suffer from graphite particles on the depositions, even when using a curved solenoid.
