Friction and Electrical Contact Resistance of Iridium-Containing DLC Coatings for Electrically Conductive Tribo-Elements

Electrically conductive tribo-coatings (i.e. Ir-DLCs) were developed using a hybrid deposition process, combining RF-PECVD with DC magnetron sputtering of Ir. Pin-on-plate tribotests in reciprocating motion were performed in air on Ir, DLC and Ir-DLC coated plates against bearing steel pins under 0....
