Friction Characteristic of CrN/DLC2 Layer Deposited on AISI 304 in Contact with Al_2O_3 Ball Examined Under Atmospheric and Vacuum Conditions

摘要

The results of "ball on disc" tests for determination of the friction coefficient under the specific conditions of low and high vacuum are presented. Advanced nanocomposite coating CrN/DLC2 was deposited by plasma assisted chemical vapour deposition PACVD on AISI 304 (STN 41 7241) stainless steel plates. Friction pairs - composed from coating surface and Al_2O_3 ball examined under low vacuum reached during the tribological tests significant lower friction coefficient values than those worked under atmospheric conditions.
