Chromium and Detonation Nanodiamond Based Coatings of the Chromium–Carbon System: Deposition by Magnetron Sputtering, Peculiarities of Phase Composition, and Tribological Properties

Аннотация

The structure, the chemical and phase compositions, and the micromechanical and tribological properties of chromium–carbon coatings obtained by the magnetron sputtering of composite and/or sintered chromium–nanodiamond targets are investigated. The coatings possess the composite multiphase structure composed of chromium and its phases formed as a result of the chemical interactions of the target material’s components both between each other and with the reactive gas if present in a sputtering atmosphere. Several technological factors influencing the structural and phase peculiarities of the coatings, their nanohardness, and the dry friction behavior at high contact pressures are studied.
