Deposition and Tribological Behavior of Composite Nickel Coatings

摘要

Nickel-based composite coatings containing graphite nitrate as a dispersed phase are deposited by the electrochemical method. The process of electrodeposition of the coatings in the potentiodynamic and galvanostatic modes is studied. It is found that the sliding friction coefficient of the composite electrochemical coatings is half that of nickel coatings containing no dispersed phase. It is shown that the sliding friction coefficient of the coatings declines as the thickness of the electrolytic deposit grows.
