Amorphous carbon layers in many forms have been studied for decades and were already used in many industrial applications. These carbon layers are often used due to their good protecting, low friction and low wear properties. PACVD techniques based on discharge in hydrocarbons or hydrogen/hydrocarbon mixture is mostly used and studied. We have studied amorphous carbon and nitrogen doped carbon layers prepared by pulsed DC magnetron sputtering of graphite in argon and argon/nitrogen gas mixture. These layers were deposited on various polymer substrates that are in use in industrial transport systems. Properties like intrinsic stress, adhesion, wear resistance, friction coefficient and surface topography have been investigated. Friction and wear tests were made at conditions similar to those we expect in real transport systems. The aim of the work is to reduce energy consumption by reducing friction losses and by extending durability of coated polymer parts.
