INCREASING THE SERVICEABILITY OF FRICTION PAIRS BY APPLYING A:C:H AND A:C:H:W DLC COATINGS

Journal Title: Tribologia - Year 2010, Vol 230, Issue 2

Abstract

The paper discusses the results of structural and tribological tests conducted for a:C:H and a:C:H:W DLC coatings deposited on Co- Cr-Mo specimens using the PACVD process. The structure and morphology of the Co-Cr-Mo substrate and the DLC coating were assessed by means of a scanning electron microscope (SEM). The hardness of specimens with and without a:C:H and a:C:H:W coatings were measured under a load of 10 G applying a Matsuzawa tester (HV 0.01). The resistance of the material to tribological wear was determined by means of a T-23 microscratch tester and a T-01M ball-on-disc tester (the Al2O3 ball and the Co-Cr-Mo disc with DLC coatings) under dry friction conditions and using Ringer’s solution. The friction tests were conducted by employing a T-23 microtribometer under dry friction conditions and a T-17 pin-onplate tester under lubricated friction conditions and using Ringer’s solution. The results show that the DLC coatings increase the serviceability of the surfaces, with the a:C:H coating characterised by more stable parameters.<br/><br/>
