Friction characteristics of r. f. magnetron sputtered C and C:N thin films
Jaroslav Sobota
Abstract
Carbon and C:N layers were prepared using the commercially available Leybold-Heraeus Z 550 radio frequency magnetron sputtering plant. A graphite target of high purity (99.999 % C) was used. The tribological testing was performed with a reciprocating ball-on-disc tribometer. The sliding distance on the coating was defined as the time at which a scoring occurs, and the friction coefficient exhibits an abrupt increase. From this, and from the known amplitude of the reciprocating ball, the sliding distance was evaluated.
