Zirconia (ZrO₂) is a ceramic material having good mechanical characteristics for industrial applications. This work is an extension of previous work in which the friction coefficient and wear resistance of diamond-like carbon (DLC) films were evaluated. DLC films had attracted more interest due to their excellent physical and chemical properties, such as very high elastic modulus, high electric resistivity, high dielectric constant, high wear resistance, low friction coefficient, bio compatibility, chemically inert and thermally stable. The objective of the present study was to fabricate DLC thin film coatings on ZrO₂ alloy surface using Plasma Enhanced Chemical Vapor Deposition (PECVD) method and evaluation of Vickers hardness. This work is focused due to high demand of DLC coated ceramic materials and it was concluded that, DLC coatings helps to improve the Vickers hardness of ceramics.
